Question

 ∠A = 60° , ∠ B = 90° , ∠ C = 30° , forms a triangle . true or false​

Answer 1

True,
Because all the angles in an triangle add up to 180 degrees.

If we add 30+60+90 degrees
We will get,90+90=180degree

Therefore these measures form a triangle.

Answer 2

if we add all angles then

they are equal to 180...

then it is a triangle
