Congruence of regular geometric shapes
From Karnataka Open Educational Resources
This activity involves in identifying the congruent shapes among the shapes of different geometric shapes.
Objectives
To understand congruence in different geometric elements and shapes
Estimated Time
15 minutes
Prerequisites/Instructions, prior preparations, if any
Prior knowledge of point, lines, angles, parallel lines
Materials/ Resources needed
- Digital : Computer, geogebra application, projector.
- Non digital : Worksheet and pencil.
- Geogebra files : “Congruence Introduction different shapes.ggb”
Process (How to do the activity)
- For each set of shapes the following can be discussed
- What are these shapes?
- Which among them are exactly same?
- How can you say that they are congruent?
Evaluation:
- Students should understand when two shapes coincide then they are congruent
- Students should be able to identify for each of the shapes which parameter determines congruence
