Basically, an isosceles triangle is a triangle that has two equal-length sides. Other than that, the third side of the triangle is unequal to the other two sides, it is called the base of the isosceles triangle. To know more about the properties of an isosceles triangle, you can read this article, till the end.<\/p>\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-definition-of-isosceles-triangle\">Definition of isosceles Triangle<\/h2>\n\n\n\n<p>An isosceles can be stated as a triangle that has two equal sides. Also, the two angles opposite at two equal sides are equal. Also, an isosceles triangle has two congruent sides. For example, if there is an isosceles triangle, whose angle B is equal to angle C. The theorem that defines an isosceles triangle is \u201cif the two sides of a triangle are congruent, then the angle opposite to them are also congruent\u201d.&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  style=\"width:447px;height:auto\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh7-us.googleusercontent.com\/docsz\/AD_4nXdy41gBgbletp-hpRBC-IbUjNbLkOsTfZ-hFr_iBUjZMm4kei8Fe2ILpcRgfvLD4c2V5GnqXh28xjWEjVQJiykowRzRzdcYeNRanzHEEEaOJLAu3S0mni4Efr4Xtxf4ICDn-mj1h5MGILMus7l7tIMmU2Mk?key=gDRBSTeeJtLEvbf22dAiqw\" ><\/figure>\n<\/div>\n\n\n<p class=\"has-electric-grass-gradient-background has-background\"><strong>Also Read: <\/strong><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-area-of-isosceles-triangle\/\"><strong>Area Of Isosceles Triangle with Solved Examples<\/strong><\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-different-angles-of-isosceles-triangle\">Different Angles of Isosceles Triangle<\/h2>\n\n\n\n<p>The two sides out of the three of an isosceles triangle are equal when measured, which are opposite to the equal sides. Therefore, the remaining angle is unequal. Take an example, if the measure of an unequal angle is provided, then the other two angles can be easily found by using the angle sum property.<\/p>\n\n\n\n<p><strong>Acute Isosceles Triangle<\/strong>: In an acute isosceles triangle, the vertex angle is the smallest angle and is less than 90 degrees. The two base angles are congruent and each is greater than 90 degrees divided by two.<\/p>\n\n\n\n<p><strong>Right Isosceles Triangle: <\/strong>A right isosceles triangle is a special case where the vertex angle is exactly 90 degrees. This makes the two base angles congruent and each equal to 45 degrees. Right isosceles triangles are also squares.<\/p>\n\n\n\n<p><strong>Obtuse Isosceles Triangle: <\/strong>In an obtuse isosceles triangle, the vertex angle is the largest angle and is greater than 90 degrees. The two base angles are congruent and each is less than 90 degrees divided by two.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-are-the-properties-of-the-isosceles-triangle\">What are the Properties of the Isosceles Triangle?<\/h2>\n\n\n\n<p>There are different properties of the isosceles triangle, some of which are stated in the given section of the article. Have a look at the given data.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The two sides of this triangle are equal and unequal.<\/li>\n\n\n\n<li>The side that&#8217;s not equal to the other two is called the base of the triangle.<\/li>\n\n\n\n<li>The two angles opposite the equal sides (legs) are congruent.<\/li>\n\n\n\n<li>If the isosceles triangle also has a right angle, then the two equal angles will each measure 45 degrees.<\/li>\n<\/ul>\n\n\n\n<p>After exploring the properties of the Isosceles triangle, you now need to solve some mathematical problems related to the isosceles triangle.

Explore the questions now.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-questions-to-practice-on-isosceles-triangle\">Questions to Practice on Isosceles Triangle<\/h2>\n\n\n\n<p>It is a time-consuming process to find the appropriate questions to practice on the isosceles triangle. To save you time, we have included some quality questions for you to practice and develop a better understanding of the concept. Have a look at it now.<\/p>\n\n\n\n<p><strong>Question 1<\/strong>: You are given an isosceles triangle ABC with AB = AC = 8 cm and angle B = 50 degrees. Find the measure of angle C.<\/p>\n\n\n\n<p><strong>Solution<\/strong>: In an isosceles triangle, the angles opposite the congruent sides are equal. Therefore, angle C is also equal to angle B. Thus, angle C = 50 degrees.<\/p>\n\n\n\n<p><strong>Question 2: <\/strong>An isosceles triangle DEF has DE = DF = 12 cm and EF = 6 cm. Find the perimeter of the triangle.<\/p>\n\n\n\n<p><strong>Solution: <\/strong>Perimeter of a triangle is the total length of all its sides added together. Since two sides are equal, the perimeter is: Perimeter = DE + DF + EF<\/p>\n\n\n\n<p>Perimeter = 12 cm + 12 cm + 6 cm = 30 cm.<\/p>\n\n\n\n<p><strong>Question 3: <\/strong>In isosceles triangle PQR, PQ = PR = 10 cm and the altitude drawn from P to base QR is 6 cm. Find the area of the triangle.<\/p>\n\n\n\n<p><strong>Solution:<\/strong> Area of a triangle is 1\/2 * base * height. In this case, base QR = PR + PQ = 10 cm + 10 cm = 20 cm.<\/p>\n\n\n\n<p>Area = 1\/2 * 20 cm * 6 cm = 60 cm\u00b2<\/p>\n\n\n\n<p class=\"has-text-align-center has-vivid-red-color has-text-color has-link-color has-medium-font-size wp-elements-798838f2749993f0611f9e8b5fcf0172\"><strong>Related Blogs<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-properties-of-rational-numbers\/\"><strong>Properties of Rational Numbers<\/strong><\/a><br><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-commutative-property\/\"><strong>Commutative Property<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-properties-of-hcf-and-lcm\/\"><strong>Properties of HCF and LCM <\/strong><\/a><br><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-properties-of-rectangle\/\"><strong>Properties of Rectangle<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-properties-of-triangle\/\"><strong>Properties of Triangle<\/strong><\/a><br><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-associative-property\/\"><strong>Associative Property <\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-faqs\">FAQs<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1721299391583\"><strong class=\"schema-faq-question\"><strong>How can you identify an isosceles triangle?<\/strong><\/strong> <p class=\"schema-faq-answer\">An isosceles triangle has two sides that are equal in length.
