Question

If one angle of a triangle is equal to the sum of other two,show that the triangle is a right triangle .​

Answer 1

Step-by-step explanation:

Since it's a right angle triangle so one angle = 90

Let, other two angles as x and x

Then, x+x = 90

2x = 90

X = 45

Here, one angle which is 90 is the sum of another two angles which 45 and 45.

And, since one angle of this triangle is 90

So, its also a right triangle
