"Axisymmetric Figures" Motion of Figures PPT Courseware 2

Description

"Axisymmetric Figures" Motion of Figures PPT Courseware 2

definition

If a figure is folded in half along a straight line and the figures on both sides of the straight line can completely overlap, the figure is an axially symmetrical figure.

The line along which the crease is located is called the axis of symmetry.

Features

The figures on both sides of the axis of symmetry completely coincide

The distance from the symmetry point to the symmetry axis is equal

Guess, cut it

(1) The above are half of the axially symmetric figures. Guess what the whole figure is?

(2) Can you cut out these shapes? Use Figure 2 in Appendix 1 to try it and talk with your partner.

give it a try

1. Which of the following figures are axisymmetric figures? Draw “√”

2. Try to circle a symmetrical figure on the nail board and talk about it with your partner.

3. Draw an axially symmetrical figure on graph paper.

4. Cut out a symmetrical axis figure that you like and display it to the whole class.
