# How many triangles can be made if two sides are 4 inches and the angle between them is 90°?

**Solution:**

Consider triangle ABC as a right isosceles triangle with an angle 90° and two sides 4 inches

So the triangles with the same measurement are congruent to triangle ABC by SAS congruence triangle.

The SAS postulate** **says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Therefore, one triangle can be made for the given measurements.

## How many triangles can be made if two sides are 4 inches and the angle between them is 90°?

**Summary:**

One triangle can be made if two sides are 4 inches and the angle between them is 90°.
