Since we may need to find the lengths of all sides of triangles to make nets and find surface area, we're going to jump to the Pythagorean Relationship unit.
In this unit, we explore the Pythagorean Theorem:
a2 + b2 = c2
This formula that can be used with right angle triangles to help you find out the side length if the two other sides are given.
