The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.
The measure of each interior angle of an equiangular n-gon is.
If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.
It is C have a great day luv
C = 180 - A - B
And
C = 180 - (A+B)
Hope I can help you :)

Answer:
Isosceles Right Triangle
Step-by-step explanation:
We look at the sides first. Two sides are equal, which means that the triangle is isosceles (equilateral means three equal sides, and scalene means no sides equal). Then we look at the only angle indicated, which is the right angle. Thus, we come to the conclusion that the triangle is an Isosceles Right Triangle.
