Question

Prove that sum of the angle of a quadrilateral ?

Answer 1

Step-by-step explanation:

draw a quadrilateral ABCD

Join A and C

So the quadrilateral is divided into two triangles

We know that sum of angles in a triangle is 180°

So

180°+180°=360°

Therefore angles of a quadrilateral add up to 360°. Thank you

Answer 2

Answer:

sum of the angles of quadrilaterals is 180 degrees..

a figure or quadrilateral sides A B C D...

AB = CD

CD= AB

Sum of the adjacent sides of the quadrilaterals are equal...

angle A B C D... are of 180...

A and B = 90 degree

C and D = 90 degrees

90= 2

2X90= 180...

hence
