Title: Identify the geometric formulas for shapes common to masonry.
Course: Masonry I (17008-I) > Section: Applying Mathematics

Identification should include

- describing the characteristics of angles and geometric shapes
- using formulas to calculate square footage (i.e., area) for rectangles, squares, triangles, and circles
- using formulas to determine perimeter, circumference, diameter, radius, volume, and angle (i.e., slope, grade) for various shapes.

Process/Skill Questions:

- What is the calculation for the hypotenuse of a triangle?
- How many degrees are in each angle of an octagon?
- Why is pi a crucial measurement?
