Document Summary
Provide a generalization to each of the key terms listed in this section. A right triangle is any triangle with one angle that is exactly 90 . A hypotenuse, which is normally labeled c in the pythagorean theorem, is the side of a right triangle that is opposite of the right angle. The legs, also known as the sides, of a triangle, which are normally labeled a and b, are connecting the right angle in a right triangle. The pythagorean theorem is a method to nd out either the hypotenuse or even one of the legs based on the given information, which can be expressed by the following formula: c2 = a2 + b2. The following are the acute angles in both degrees and radians: The following are the triangular ratios based the three sides of a triangle: a b a c b a b c c a c b.
