Lesson Plans ~ Mathematics CLG ~ School Improvement in Maryland

Geometry, Measurement, & Reasoning |

Lesson Plan: Lesson plans were written by Maryland mathematics educators and could be used when teaching the concepts.

Goal 2 Geometry, Measurement, And Reasoning

Expectation 2.2 The student will apply geometric properties and relationships to solve problems using tools and technology when appropriate.

Indicator 2.2.1 The student will identify and/or verify congruent and similar figures and/or apply equality or proportionality of their corresponding parts.

Lesson Plan
Similarity and Congruence
Approximate Time: One 30 minute lesson for the discovery lesson and up to 60 minutes for the practice, depending on how well students remember the pre-requisite skills. Objective: Students will know how to determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. Then they will know how to prove that two figures are similar or congruent by using definitions, postulates, and theorems.
