Recall what it means for an angle to be drawn in

**standard position.**(If you need a refresher,**click here**.) The applet below dynamically illustrates what it means for any 2 angles (drawn in standard position) to be classified as**COTERMINAL ANGLES.**Below, you will eventually see the formation of**one positive angle**and**one negative angle**that are both coterminal with each other. Interact with this applet for a few minutes. Then answer the questions that follow.## 1.

Without looking up the definition on another tab in your internet browser, describe, in words, what it means for any two angles (drawn in standard position) to be classified as **COTERMINAL ANGLES.**

## 2.

a) Is it possible for two **positive angles** drawn in standard position to be coterminal?
b) If so, can you provide the measures of any two **positive angles** that are cotermainal?

## 3.

a) Is it possible for two **negative angles** drawn in standard position to be coterminal?
b) If so, can you provide the measures of any two **negative angles** that are cotermainal?
