T.i.P.S.

Students must be able identify twodimensional figures based on attributes of having or not having parallel lines, perpendicular lines, or angles with certain measurements.
Example

Use the following diagrams to answer the questions below.1. Which shapes have all sides congruent?
2. Which shapes have all angles congruent?

4.6 Geometry and measurement. The student applies mathematical process standards to analyze geometric attributes in order to develop generalizations about their properties. The student is expected to:(D) classify twodimensional figures based on the presence or absence of parallel or perpendicular lines or the presence or absence of angles of a specified size
