Identify the basic geometric formulas for shapes common in construction.

Identification should include formulas for

• calculating square footage (i.e., area) for rectangles, squares, triangles, and circles
• determining
  • perimeter
  • circumference
  • diameter
  • radius
  • volume
  • angle (i.e., slope, grade).

Process/Skill Questions:

• What is the formula for the hypotenuse of a triangle?
• How many degrees are in each angle of an octagon?
• What is pi, and how is it used in construction? Why is pi a crucial mathematical constant?
