Question

please give me answer​

Answer 1

If sum of all the angles is 180° then it can form a triangle

1) 60+60+60 = 180°

2) 100+80+50=220°

3)68+48+78=194°

4)75+75+70=220°

Therefore only the 1st case will make a triangle

Answer 2

1) angle A = 60

angle B = 60

angle C= 60

solution

angle A+angle B+angleC=180

60+60+60=180
120+60=180
180=180

therefore this three angle can form a triangle.

in this way you can solve the other questions easily

I hope it is help full
