Texas Essential Knowledge and Skills: Geometry

10. The student applies the concept of congruence to justify properties of figures and solve problems.

8. The student uses tools to determine measurements of geometric figures and extends measurement concepts to find perimeter, area, and volume in problem situations.

6. The student analyzes the relationship between three- dimensional geometric figures and related two-dimensional representations and uses these representations to solve problems.

7. The student understands that coordinate systems provide convenient and efficient ways of representing geometric figures and uses them accordingly.

5. The student uses a variety of representations to describe geometric relationships and solve problems.

4. The student uses a variety of representations to describe geometric relationships and solve problems. The student is expected to select an appropriate representation (concrete, pictorial, graphical, verbal, or symbolic) in order to solve problems.
