Description

"Making Axisymmetric Figures" Axisymmetric PPT Courseware 2

Review old knowledge

1. If a figure is folded along a straight line and the parts on both sides of the straight line can overlap each other, the figure is called an axially symmetric figure.

2. If two figures are symmetrical about a straight line, then the axis of symmetry is the perpendicular bisector of the line segment connecting any pair of corresponding points.

Axisymmetric transformation

Obtaining an axially symmetrical figure from a plane figure is called axially symmetrical transformation

Nature of inquiry:

1. From a plane figure, we can obtain a figure that is axially symmetrical about a straight line L. This figure has exactly the same shape and size as the original figure.

2. Every point on the new graph is a symmetry point of a certain point on the original graph with respect to the straight line L.

3. The line segment connecting any pair of corresponding points is bisected perpendicularly by the axis of symmetry.
