## Sagot :

**Answer:**

There is a right angle and it has three sides.

**Explanation:**

There are two 45 degree angles and since a triangles sides ALWAYS add up to 180 we know the the other side has to be 90 degrees because 45+45+90=180. And we know that every triangle has three sides because "tri" means three.

An isosceles right triangle has a right (90°) angle and two equal sides.
