Question

Prove that the sum of angles in any triangle is equal to two right angles

Answer 1

Two right angles = 90 + 90

Two right angles = 180°

=================

To prove:- sum of angles of a triangle is 180°

Used Formula :- (2n-4)×90 [n = no.of sides of quadrilateral]

Proof :-

Triangle has 3 sides,

Applying formula,

(2n - 4)×90 = sum of angles of triangle


(6-4)×90 = sum of angles of triangle

180 = sum of angles of triangle


=================

Hence, proved

180 = 180


I hope this will help you
