Question

The sum of two angles of a triangle is equal to its third angle. Find the third angle. What type of triangle is it?​

Answer 1

Answer:

Finding the Third Angle in a Triangle. The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.

Answer 2

Answer:

hey

heres your answer

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.
