Question

If sum of two angle is equal to third angle TPT Triangle is right angle triangle

Answer 1

Let the first and second angle be a and b respectively 

Third angle = a+b


By angle sum property of triangle 

a +b + a+b = 180

=> 2a +2b = 180

=> 2(a+b) = 180

=> a+b = 90°

Third angle = 90°

Answer 2

Answer: hope it helps u buddy!!!!!! but i think the question is incomplete but still i did

Step-by-step explanation:

Let measure of two of its equal angles be x°

And, third angle be y°

Then, x°+x°= y°

But, according to angle sum property of a triange,

Sum of all angles of a triangle = 180°

So, x°+x°+y°= 180°

=> y°+y° = 180°

=> 2y° = 180°

Therefore, y = 90°

Hence, other angles are 45°

We can call this angle as Right isosceles triangle.
