ACTIVITY – 2. Tangram Activity

DATE:

 

AIM / Objective:

To find Congruence of triangles

 

MATERIALS REQUIRED:

Pencil, scale, eraser

 

PREREQUISITE KNOWLEDGE:

Concept of Congruence of triangles

 

PROCEDURE:

Description:

Students will be made to cut the 7 pieces of a tangram from the following figure.

 

LEARNING ASSESSMENT:

 

1. Find two pairs of congruent triangles from the 7 given pieces.

2. Make a triangle using the congruent triangles 4 and 5.

Place this triangle on the triangle 3.

3. Is the new triangle congruent to the triangle 3?

4. Make a square using two congruent triangles 1 and 2.

Is this square congruent to the original square piece from which the tangram set was made? Give reasons.
