The angles are labeled with capital letters and the sides are labeled with lower case letters that match the angle on the opposite side of the triangle.
Read the following
A right triangle is a triangle that has one right angle. A right angle has a . measure of 900. The right angle of a right triangle is denoted by a square.
1. The side directly across from Ð A is called the opposite side. So a is the opposite side of this triangle.
The angles are labeled with capital letters and the sides are labeled with lower case letters that match the angle on the opposite side of the triangle.
2. The side opposite the right angle is called the hypotenuse. So c is the hypotenuse of this triangle.
3. The remaining side is the adjacent side. It's the side of the angle which
ends at the right angle.
Side b is the side adjacent to Ð A.
