5-22-23 Lesson Plans for Geometry

Standards Addressed

MGSE9-12.G.SRT.5  Use congruence criteria for triangles to prove relationships in geometric figures

MGSE9-12.G.CO.7  Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.

MGSE9-12.G.CO.8 Explain how the criteria for triangle congruence follow from the definition of congruence in terms of rigid motions.

MGSE9-12.G.CO.13  Construct a hexagon inscribed in a circle

MGSE9-12.G.SRT.4  Prove theorems about triangles

MGSE9-12.G.CO.11  Prove theorems about parallelograms

MGSE9-12.G.SRT.2  Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain, using similarity transformations, the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides.

MGSE9-12.G.SRT.3  Use the properties of similarity transformations to establish the AA criterion for two triangles to be similar

MGSE9-12.G.SRT.5  Prove theorems about triangles: A line parallel to one side of a triangle divides the other two proportionally.

MGSE9-12.G.SRT.1  Verify experimentally the properties of dilations given by a center and a scale factor.

Learning Targets/Success Criteria        

I can solve problems involving congruent figures by:

     -completing geometric proofs 

     -identifying corresponding parts of congruent figures

     -identifying congruent triangles using SSS, SAS, AAS, ASA, and HL.

I can construct a hexagon inscribed in a circle by

     -using compass and straightedge
