Question

Prove that the sum of angles of a quadrilateral is 360°
​

Answer 1

Step-by-step explanation:

A quadrilateral is a polygon which has 4 vertices and 4 sides enclosing 4 angles and the sum of all the angles is 360°. When we draw a draw the diagonals to the quadrilateral, it forms two triangles. Both these triangles have an angle sum of 180°. Therefore, the total angle sum of the quadrilateral is 360°.

mark as brilliant ans take thanks for all question

Answer 2

A quadrilateral is 360°

so the each side of a quadrilateral=360÷4=90
