Geometry: Corresponding Parts of Congruent Triangles
by Texas Instruments - Action Consequence Lesson

Updated on June 13, 2014

#### Objectives

• Students will identify corresponding parts of congruent triangles.
• Students will use appropriate notation to describe two congruent triangles.
• Students will reason abstractly and quantitatively (CCSS Mathematical Practice).

#### Vocabulary

• corresponding parts
• congruent triangles

In this lesson students will investigate corresponding parts of congruent triangles. As a result students will:

• Manipulate given segments and angles to form a triangle that is congruent to a given triangle.
• Identify the corresponding parts for the triangle they formed and the given triangle.
• Manipulate two triangles to visually map the corresponding parts to each other.
• Write and interpret congruence statements using notation that designates the corresponding parts.
