Isosceles Triangle Worksheet Answer Key

This is a non-intimidating way to prepare students for formal geometry lessons. The Geometry Key Workbook introduces students to a variety of geometric shapes that they learn through construction. Using a pencil, compass, and ruler, students begin to draw lines, divide sides, and create lines. Then they need to build a tall building with ten or more steps to create a common structure. Upon completion, students will be familiar with 134 geometric terms and ready to tackle formal proofs.
