### Rustine's Growing Post

#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.

rotational symmetry: is symmetry with respect to some or all rotations, has the ability to turn 360 deegres and still keep its shape.

reflection symmetry: a symmetric transformation in which a figure is reversed along an axis so that the image looks as though it is in front of a mirror.

#2 - QuestionCreate 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.

The steps are listed in the picture.

#3 - QuestionDescribe in words what is occurring with your pattern and if your pattern has an ending or if it continues on indefinitely. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

In my pattern it looks like the number 'L', you begin with 5 cubes. In my pattern it adds 1 cube to the horizontal part of the letter 'L'. With every step, the horizontal part of my letter gets longer and longer. My pattern never ends .

#4 - QuestionCreate 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.

Mr. Reece .. i had some trouble with the pictures . SORRY .

Rustine hand in the pictures in order to get full marks.

As well you did not mention how pentominoes relate to reflection and rotation symmetry.

As well you might want to mention the number of cubes that are horizontal and vertical

I like to get up early to go out and breathe fresh air. I feel that it is good for health and a good habit
