Description

"Axisymmetric" graphics motion PPT courseware

Symmetry phenomena are everywhere, from natural landscapes to molecular structures, from buildings to works of art, and even daily necessities, people can find examples of symmetry.

Facing these beautiful pictures in life, do you strongly feel that beauty is all around us? What kind of beauty is this? Could you please share your thoughts?

Come into today's class and you'll be able to explain the mystery!

Really? I have to listen carefully! See if you are lying to me!

Experiment 1: Explore new knowledge

Please think about it: Can you fold each shape in the picture above along a straight line so that the parts on both sides of the straight line completely overlap?

If a figure can be folded in half along a straight line, and the two folded parts are completely coincident, then such a figure is called an axially symmetric figure, and this straight line is called the axis of symmetry of the figure.

Like this, if a figure can be folded along a certain straight line and it can overlap with another figure, then the two figures are said to be axially symmetrical.

We call this line their axis of symmetry, and the corresponding points in the two figures (that is, the points that overlap each other when the two figures overlap) are called symmetry points.

Use your brain, think about it, and talk about it:

Can you give some common examples in daily life where two figures are axially symmetrical?

If you can't think of it, it doesn't matter. We can first look around us to see if there are any? Think again, are there any out there?

"Axisymmetric" PPT:

"Axisymmetric" PPT Part 1 Content: New Lesson Introduction What characteristics did you find of these buildings? There are many symmetrical things and phenomena in life. Boats, people, plants and reflections in the water are all symmetrical. Take a small mirror and place it on an axially symmetrical figure or object...

"Axisymmetric" PPT Courseware 6 If a figure is folded along a straight line, and the parts on both sides of the straight line can overlap each other, then the figure is called an axially symmetric figure, and this straight line is called the axis of symmetry. Practice it. The following figures are all axially symmetrical figures. Please find out...

"Axisymmetric" PPT courseware 5 Review of old knowledge What is an axially symmetric figure? What is the axis of symmetry? If a figure is folded along a straight line and the parts on both sides of the straight line can completely overlap, the figure is called an axially symmetric figure. This straight line is called the axis of symmetry.
