 Innovative Model on Equal Triangles – Geoboard Activity

The images above show an innovative working model on the chapter Equal Triangles, prepared using a Geoboard. This model visually demonstrates the five congruence principles of triangles, helping students understand abstract concepts through hands-on learning.

Congruence Principles Demonstrated

SSS (Side–Side–Side) Rule

If the three sides of one triangle are equal to the three sides of another triangle, the two triangles are congruent.

SAS (Side–Angle–Side) Rule

If two sides and the included angle of one triangle are equal to the corresponding two sides and angle of another triangle, the triangles are congruent.

ASA (Angle–Side–Angle) Rule

If two angles and the included side of one triangle are equal to the corresponding two angles and side of another triangle, the triangles are congruent.

AAS (Angle–Angle–Side) Rule

If two angles and a corresponding non-included side of one triangle are equal to those of another triangle, the triangles are congruent.

RHS (Rightangle–Hypotenuse–Side) Rule

In right-angled triangles, if the hypotenuse and one corresponding side are equal, the triangles are congruent.

Use of Geoboard in Learning

The Geoboard plays a significant role in mathematics learning as it promotes visualization, accuracy, and active participation. By forming triangles using elastic bands and pegs, students can easily compare sides and angles, verify congruence rules, and correct misconceptions through experimentation.

Learning Outcome

This Geoboard-based model encourages activity-based and constructivist learning, allowing students to observe, explore, and conclude the congruence of triangles on their own. The hands-on experience makes the learning process engaging, effective, and memorable.
