Question

prove sum of all angles of a quadrillateral is 360°​

Answer 1

Answer:

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°.

Thanks plzzz

Answer 2

we draw one diagonal to quadrilateral we will get two triangles and we know that sum of the angles of a triangle is 180°

180 + 180

360°
