Welcome to the Similar and Special Right Triangles Homepage. Here you can learn about how similar and special right triangles can help find alternate ways to find the values of different parts of the triangles. Below are a few definitions to words you will need to know in order to understand the content on this site.
Altitude: A perpendicular line drawn from the vertex of a triangle to the base. The altitude measures the height of a triangle.
Hypotenuse: The side of a right triangle opposite the right angle. In the Pythagorean theorem, leg-a squared + leg-b squared = hypotenuse squared.
Leg: Either of the two sides of a right triangle adjacent to the right angle, or, in a triangle that is not right, adjacent to the vertex. Legs of an isosceles triangle are always congruent.
Side: One part of the hypotnuse of the larger triangle.
Right Angle: An angle measuring ninety degrees. If such an angle is one of the three angles of a triangle, then the triangle is known as a right triangle.
Similar Triangles: A pair of triangles that has two equal angles; the sides are not necessarily equal. Similar triangles make the equation AA=AA true.
