Congruent Shapes and Symmetry

Congruent Show video 15-4 on

You have learned that figures related by translations, rotations and reflections are the same size and shape. Today, you will learn to use these relationships to test if two figures are the same size and shape. Using your tangram pieces, find the following pairs:  A congruent pair-same size and shape  A pair with different sizes but the same shape  A pair with different size and shape. Congruent Figures How can we use translations, rotations and reflections to prove figures are congruent?

Congruent pairs are the same size and shape. What pairs did you find? Why are the figures in each of these pairs congruent? Which pairs of pieces did you find that are not congruent? Why aren’t these figures in these pairs congruent? Congruent Figures How can we use translations, rotations and reflections to prove figures are congruent?

Symmetry Show video 15-5 on

You have just learned that figures related by reflection are the same size and shape, so how can we use this relationship to identify symmetry? Give each student a piece of construction paper. Fold and cut into a snow flake to demonstrate symmetry. Line of Symmetry How can we use reflections to verify that a shape has symmetry?

What is a line of symmetry? What does it mean for a shape to be symmetrical? Symmetrical means it can be folded on a line to form two congruent halves that fit on top of each other. A line of symmetry is the fold line that separates the congruent sides. A figure can have many lines of symmetry. A figure can have no line of symmetry too.

How can we make a design symmetrical? Today you’ll be making two symmetrical designs with your partner, and if you have time, one design that is not symmetrical. 1.Draw your line of symmetry. 2.Select your first polygon. 3.If we are going to make a symmetrical design, what block should we put on the other side of line, and where should we put it? 4.Repeat with additional shapes… 5.Create two shapes with your partner.

Discussion: Symmetry Share designs. If we say something has symmetry, what do we mean? We know all of our designs have at least one line of symmetry. Do any of them have more than one line of symmetry?
