1.12-1.13 Geometry--Symmetry
Use the activity above. What is the difference between an exterior angle and an interior angle (in your own words)
In the activity above, what is the measure of an exterior angle of a 12 sided regular polygon? Using the formula show the work that can be used to solve this problem.
In the activity above, what is the measure of one interior angle in a regular 8 sided polygon. Use the formula to show your work on how to get the answer.
What is the formula for the sum of all the interior angles in any polygon (regular or not). Use this formula to find the sum of all interior angles in a 5 sided polgyon? 6 sided?
Show all of your work.
In the figures below, name the figures that have reflection symmetry. If so, how many lines of reflection does each have?
