Question #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

1.Rotation symmetry means that if you can turn or rotate a figure or shape around a center point in less then 360 degrees and the shape doesnâ€™t look different or unchanged that means that the shape has t rotation symmetry. Reflection symmetry means that a shape or figure will have a mirrored image of the shape which makes it look unique but when the shape is flipped or they will look the same. Reflection symmetry and rotation symmetry are related to pentomines in different ways.

One way is that if you take this pentominoe(letter "L") and turn it, it will look the same or unchanged, just in a different position.

Another way is that if you take a pentominoe with reflection symmetry like this one. They are the same shape but when you turn it, it looks different but they are not.

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

2. This is a pattern that I have created:

step one has 2 blocks. step two has 3 blocks. step three has 4 blocks. step four has 5 blocks

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

3. My pattern starts of with 2 blocks beside each other. Then in step 2, 1block is added horizontally to make is 3 blocks in length. The 3rd step will now add another block beside it to make a total of 4 boxes in step 3. After, I added 1 more block beside the 4 boxes to make a total of 5 boxes. My pattern could go on and on and you could solve any step if you use its algebraic formula.(step # +1 =#of boxes, e.g. step 300: 300+1=301 boxes.)

Question #4: Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

4. Now I have created a T-chart using the information from my pattern.
