-A right triangle has three sides and an angle that equals 90º.
-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 on 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:
-:<math>a^2 + b^2 = c^2</math>
-The analysis of ratios between sides of right triangles with hypotenuse = 1 is at the heart of [[trignometry]].
