Geometry (Class 50)
Lesson Title
Areas of Quadrilaterals 1
Overview
In today’s class our warm-up focuses on clarifying the hierarchy and interrelationships between quadrilaterals. We then turn our attention to developing formulas for the area of quadrilaterals based on breaking quadrilaterals up into triangles. Finally during the last 40 minutes of class we will be writing Test 7.
