A '''right triangle''' has three sides and an angle that equals 90º - that is, a [[right angle]].
A '''right triangle''' has three sides, with an angle that equals 90º - that is, a [[right angle]].
The general right triangle is the subject of one of the more famous mathematical ideas, the [[Pythagorean Theorem]]. It states that the sum of the squares of the legs (short sides) of a right triangle is equal to the square on the [[hypotenuse]] (the long side, opposite the [[right angle]]). Using the figure to the right, this means:
