Polygons are congruent if they are the same size and shape that is, if their corresponding angles and sides are equal. The activity helps in identifying congruent shapes.
Objectives
- Identify congruent shapes
- Understand shape and size
Estimated Time
30 minutes
Prerequisites/Instructions, prior preparations, if any
Prior knowledge of point, lines, angles, parallel lines, closed figures
Materials/ Resources needed
- Digital : Computer, geogebra application, projector.
- Non digital : Worksheet and pencil
- Image files :
Process (How to do the activity)
- Use the image files to illustrate
- How many things do you see that are same
- Point out the things that are same.
- Things that are same but different in colour
- Things that are same but different in size
- Things that are same that are same shape and size
- Point out different shapes that are formed with existing shapes
- HW: Observe regarding shapes
- If two figures are the same shape, are they the same size?
- If two figures are the same size, are they the same shape?
Evaluation at the end of the activity
- Students should be able to identify same shapes that are of different sizes.
- Students should be able to understand that different shapes can have same size
- The teacher can ask students to think of many objects which are mass-produced and that are found to be exactly the same size and shape like pens, CD-roms, cars etc.
