Description

"Congruence of Figures" Triangle PPT Courseware

learning target:

1. Understand the concept of congruent graphics.

2. Be able to identify congruent polygons (triangles) and their corresponding vertices, corresponding angles and corresponding sides.

3. Know the characteristics that the corresponding sides and corresponding angles of congruent polygons (triangles) are equal.

4. Through hands-on operation, you can realize that folding, rotation and translation are the main methods to observe the congruence of two figures, and you can find the corresponding vertices, corresponding sides and corresponding angles.

Self-study tips:

Congruent polygons: Polygons that can be transformed (completely coincident) through graphical transformation.

Corresponding elements: Vertices that overlap each other are called (corresponding vertices);

The sides that overlap each other are called (corresponding sides;)

Angles that overlap each other are called (corresponding angles;)

congruent symbol (≌)

Characteristics of congruent polygons (triangles): (Corresponding sides and corresponding angles of congruent polygons (triangles) are equal.)

Identification of congruent polygons (triangles): (two polygons (triangles) whose sides and angles correspond to equal values) are congruent.
