TO SHOW THAT SUM OF ALL INTERIOR ANGLE OF A TRIANGLE IS 180 . WITH DIAGRAM

${\huge{\boxed{\sf{\pink{✰Answe࿐✰}}}}}$

☞ - Sum of a triangle's interior angles have the measure of 180° .

☞ - By angle sum property of a triangle.

FOR EXAMPLE:-

Find the measure of the third side of a triangle whose each angle is having the measure of 60° .

Solution

Let the third side be = x

By angle sum property of a triangle

60°+60°+ x= 180°

120° +x= 180°

x= 180°-120°

x=. 60°

Therefore, x= 60° .

• From this example we can show that the sum of interior angles of a triangle are always 180° .
