Special Right Triangles
45-45-90
Since it is isosceles the two leg lengths are the same and
the hypotenuse is multiplied by √2
30-60-90
The hypotenuse is double the length of the opposite of 30°
The Adjacent side is the opposite side multiplied by √3
Pythagorean Theorem
The square of the hypotenuse is the sum of the legs
