About Geometry Worksheet Assignment 8.6:                   

 

Assignment 8.6 is an introduction to areas of triangles.

 

Prerequisite Skills:  Find areas of polygons by counting squares in their interiors (Assignment 8.1).  Measure lengths to the nearest cm. (Assignment 1.11).  Solve algebraic equations with one variable.

 

Theorems:  The area of a triangle is one-half the product of the length of its base and its height.
