22 Pythagorean Theorem
The equation for the Pythagorean theorem is A2 + B2 = C2
Where A and B are the lengths of the two legs of the triangle, and C is the length of the hypotenuse.
We use special words to describe the sides of right triangles.
The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle.
A right triangle always has one 90 degree angle.
The other two sides are called the opposite and adjacent sides. These sides are labeled in relation to an angle.
The opposite side is across from a given angle.
The adjacent side is the non-hypotenuse side that is next to a given angle.
Note: If the side opposite the right angle is the hypotenuse and the side across the given angle is the opposite, then the remaining side has to be the adjacent.
