The image has an order of rotation: 2. The angle of rotation is 180 degrees. So, therefore it has rotation symmetry.
I'm going to show you another question from the test. Here it is:
Find the angle of rotation for the following image:
The angle of rotation is: 60 degrees.
Those are two of the questions that was on the test.
We had a few homework for today
1) Provide an algebraic formula for finding the surface area of a rectangular prism.
2) Provide a formula for finding the surface area of a cylinder.
*Then, when we come to class, we should be able to explain, make a net, and be able to talk about the symmetry of the shapes. (for rectangular prisms and cylinders)
3) Write in our journals.
4) Last but not least, comment on my post! :)
The next scribe is Aleiah. The homework is due. next class. So you better get going!
