Right triangle with angle measurements 90-45-45 Special right triangle. the hypotenuse is equal to the square root of 2x Right triangle with angle measurments 90-60-30 Special right enuse is 2x. the short side is x and the long side is square root of 3x Quadrilaterals A closed, 4 sided shape. The sum of all 4 sides is always equal to 360. The AREA of quadrilateral is always A= bh (base time height) Parallelogram A quadrilateral with two pairs of equal side. Two consecutive sides in a parallelogram are supplementary = 180 Rectangle
