## What is Quadrilateral? What are Quadrilateral Problems?

A quadrilateral is a plane shape with four sides (edges) and four corners (vertices). The quadrilateral’s angles can be found at its four vertices or corners. In a quadrilateral ABCD, the angles at the vertices are A, B, C, and D, respectively. The sides of a quadrilateral are AB, BC, CD and DA.

## Quadrilateral Formulas for Different Quadrilateral Types

Here we have mentioned some of the important quadrilateral formulas for different quadrilateral types:

Quadrilateral Type | Quadrilateral Formula |

Square | = s x s, s is the side. |

Rectangle | = l × b |

Rhombus | = d1 x d2/2d1 and d2 are diagonals. |

Parallelogram | = b × h |

Trapezium | = [(a + b)h]/2 |

Isosceles Trapezium | = [(a + b)h]/2 |

Kite | = d1 x d2/2d1 and d2 are diagonals. |

**3 angles of a quadrilateral are respectively equal to 110°, 50° and 40°. Find its fourth angle.**

**Solution:**

Given,

The 3 angles are 110°, 50° and 40°

Let, the fourth angle be ‘x’

Sum of all angles of a quadrilateral = 360°

110° + 50° + 40° + x = 360°

200° + x = 360°

x = 360° − 200°

x = 160°

Hence, the required fourth angle is 160°.
