A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one ...
A right triangle ABC with its right angle at C, hypotenuse c, and legs a and b,. A right triangle or right-angled triangle, sometimes called an orthogonal triangle or rectangular triangle, is a triangle in which two sides are perpendicular, forming a right angle (1 ⁄ 4 turn or 90 degrees).
A Kepler triangle is a right triangle formed by three squares with areas in geometric progression according to the golden ratio. A Kepler triangle is a special right triangle with edge lengths in geometric progression .
In a right triangle two of the squares coincide and have a vertex at the triangle's right angle, ... A special case of concave circular triangle can be seen in a ...
Special cases are right triangles (p q 2). Uniform solutions are constructed by a single generator point with 7 positions within the fundamental triangle, the 3 corners, along the 3 edges, and the triangle interior.

English: This file illustrates the special right triangle of angles 30°, 60° and 90°. A black square represents the borders of the file. Inside, the triangle is depicted with all of its special angles. The right angle is symbolized by a small square, and its measure, 90°, is written to the right and above it.
The difference between these two definitions is that the modern version makes equilateral triangles (with three equal sides) a special case of isosceles triangles. [2] A triangle that is not isosceles (having three unequal sides) is called scalene. [3] "Isosceles" is made from the Greek roots "isos" (equal) and "skelos" (leg).
