Special Right Triangles 1 Two Special Right Triangles 45° 45° 90° 30° 60° 90° 2 45° 45° 90° The triangle is based on the square with sides of 1 unit 1 1 1 1 3 45° 45° 90° If we draw the diagonals we form two triangles 45° 45° 45° 45° 1 1 1 1Triangle triangles are special right triangles with one 90 degree angle and two 45 degree angles All triangles are considered special isosceles triangles The triangle has three unique properties that make it very special and unlike all the other triangles Segment AF is therefore the long leg of this triangle, with a length of √3 AF, length √3, and FC, the short leg of the triangle, together form dodecagon radius AC, already set at length 2 By length subtraction, then, FC, the triangle's short leg, has a length of 2 – √3
