DIRECTIONS
1. DEFINITIONS OR FORMULAS
For each vocabulary term or formula, write out the definition of the term or give the formula. If
you are giving a formula, define your variables (e.g., don't write just A = b x h, write Area = Base
x Height or A = b x h, and define A = area, b = base and h = height).
2. SKETCH
A simple sketch (picture) is required for each term unless specified by: NO PICTURE. For terms
that require a sketch; draw a simple and labeled sketch of the item you are defining.
Recommendation: Don't waste time on fancy graphics
