Graphs with Algebra and Geometry

Sketch graphs of the following on the Cartesian Coordinate Plane:

1. The sum of the measures of the interior angles (on the y-axis)

versus the number of sides of a given polygon (on the x-axis).

2. The sum of the measures of the exterior angles versus the

number of sides of a polygon.

3. The measure of one interior angle of a regular polygon

versus the number of sides in that regular polygon.

A. How many degrees would one interior angle of a regular 90-sided polygon have?

B. Write a formula for f(n) =

4. The measure of one exterior angle of a regular polygon

versus the number of sides in that regular polygon.

Write a formula for f(n) =
