Right Triangle -- from Wolfram MathWorld
A right triangle is triangle with an angle of 90 degrees (pi/2 radians). The sides a, b, and c of such a triangle satisfy the Pythagorean theorem a^2+b^2=c^2, (1) where the largest side is conventionally denoted c and is called the hypotenuse. The other two sides of lengths a and b are called legs, or sometimes catheti. The favorite A-level math exam question of the protagonist Christopher in ...
Right triangle definition - Math Open Reference
Properties. A right triangle can also be isosceles if the two sides that include the right angle are equal in length (AB and BC in the figure above); A right triangle can never be equilateral, since the hypotenuse (the side opposite the right angle) is always longer than either of the other two sides.; Constructions. You can construct right triangles with compass and straightedge given various ...
Special right triangle - Wikipedia
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 right triangle is a triangle that has a 90 degree angle as one of its angles. This page will allow you to calculate things related to a right triangle.
Isosceles Right Triangle -- from Wolfram MathWorld
A right triangle with the two legs (and their corresponding angles) equal. An isosceles right triangle therefore has angles of 45 degrees, 45 degrees, and 90 degrees. For an isosceles right triangle with side lengths a, the hypotenuse has length sqrt(2)a, and the area is A=a^2/2. The hypotenuse length for a=1 is called Pythagoras's constant.

Trigonometry Word Problems. Here are some types of word problems that you might see when studying right angle trigonometry.. Note that the angle of elevation is the angle up from the ground; for example, if you look up at something, this angle is the angle between the ground and your line of site.. The angle of depression is the angle that comes down from a straight horizontal line in the sky.
