The 5 12 13 triangle is an SSS special right triangle with the ratio between its side lengths as 5, 12, and 13 It is a common Pythagorean triple that is worth memorizing to save time when dealing with right triangles The other common SSS special right triangle is the 3 4 5 triangle. The typical sidebased unique right triangles are Triangle 345 Triangle The triangular name defines the proportion of side sizes. "Anglebased" special right triangles are specified by the relationships of the angles of which the triangle is composed The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π / 2 radians, is equal to the sum of the other two angles The side lengths are generally deduced from the basis of the unit circle or other geometric methods.
