They all have 3 angles 3 verticals and 3 sides .

Use auto shapes to draw a tessellation below

This illustration is a tessellation because…….

It fits together with no gaps .

Using your chart, explain the pattern you see in Column A.

The pattern is that you add one each time .

Using your chart, explain the relationship between the numbers in Column A and Column B.

The relationship between column a and column b is you just add one but column b starts at 3

Using your chart, describe the pattern you found in Column E.

In column e you just add 180.

Explain how you found your answer to the 150-sided figure. How do you know that your answer is correct?

150 sided figure

8640

I know my answer is correct because 150 – 148 and 148 x 180 is 8640 .
