Congruence of regular 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)
Evaluation:
 * 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?
 * 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
