Transcript of Kungfu math p4 slide23 (symmetry)pdf

• identifying symmetric figures • determining whether a straight line is

a line of symmetry of a symmetric figure

• completing a symmetric figure with respect to a given horizontal/vertical line of symmetry

What will we learn today?

Geometry Symmetry

Let's find symmetry in shapes!

Symmetric Figures

You can find if a shape has a Line of Symmetry

by folding it.

When the folded part sits perfectly on top

(all edges matching), then the fold line is a

Line of Symmetry.

Symmetric Figures

When the folded part sits perfectly on top

(all edges matching), then the fold line is a

Line of Symmetry.

Symmetric Figures

Try folding it this way!

When the folded part sits perfectly on top

(all edges matching), then the fold line is a

Line of Symmetry.

Symmetric Figures

Try folding it this way!

When the folded part sits perfectly on top

(all edges matching), then the fold line is a

Line of Symmetry.

This is line of symmetry.

Try this out! Find the line of symmetry.

Is this the line of symmetry?

No, it is not the line of symmetry. The line does not cut the figure into equal shapes.

Solution
