Question

prove that the sum of the angle of triangle is equal to two right angle or 180°​

Answer 1

Answer:

Step-by-step explanation:

the sum of angles of a triangle = angleA + angleB + angleC = 180............(1)

right angle = 90 so, 2*90 = 180...........(2)

so sum of all the angles of a triangle from eqs 1 n 2 is 2*90 i.e. 2 right angles

Answer 2

Answer:

a+b+c=180°

a=b=c

3a=180°

3b=180°

3c=180°

a=60°b=60°c=60°
