Question

angle sum property of quadrilateral

Answer 1

suppose 4 angles of quad r a,b,c,d then
angle sum property=
angle a+b+c+d=360 degree

Answer 2

Answer:

Property:

The sum of the interior angles of a quadrilateral add up to 360⁰

Proof:

Draw a diagonal of the quard you will get 2 triangles

By angle sum property of triangle

Angles of 1st triangle = 180⁰

Angle of 2nd triangle = 180⁰

Sum of the angles of 2 triangle = 360⁰
