30°-60°-90° Triangle- It is a special right triangle. In a 30°-60°-90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times square root of 3.
Symbol:30°-60°-90°△
Segment AC is the square root of 3 multiplied by the value of AB and Segment BC is the value of segment AB multiplied by 2.
I chose these because they are all important factors of triangles and their measures. They all help find missing measures or help classify triangles.
