Answer:
C. Right isosceles
Step-by-step explanation:
We have 2 angles that are the same, that means two sides have to be the same. That makes the triangle isosceles
There are 3 angles in a triangle. They add to 180
45+45+x = 180
90+x=180
90-90+x=180-90
x=90
The other angle is a 90 degree angle. A ninety degree angle is a right angle.
That makes the triangle a right isosceles triangle
