Step-by-step explanation:
We know that the sum of the angles of a triangle is 180°. ⇒ ∠A + ∠B + ∠C + ∠D = 360° [using (i) and (ii)]. Hence, the sum of all the four angles of a quadrilateral is 360°.
to prove sum of all angles of a quadrilateral is 360.
Step-by-step explanation:
sum of all angles of n-sided polygon = 180(n-2)
where n is number of side
quadrilateral has 4sides
sum of all angles =180
180(4-2)=180*2
360..
