Definition
A trapezoid is a quadrilateral with at least one pair of parallel sides.
Main properties
- The parallel sides are called bases.
- Measurements must use the same unit before calculating.
- Draw a quick sketch to identify each value.
Formula
Area = ((B + b) x h)/2.
Example method
Read the problem, mark the known measurements, choose the formula and simplify the result step by step.
