# Angles and Sides

Look at the two triangles provided. Only one vertex differs between the two.

- How do the angle measures compare to the side lengths they are opposite to?
- Which angle is opposite the longest side: the smallest, largest, or middle-size angle?
- Which angle is opposite the shortest side: the smallest, largest, or middle-size angle?
- Which angle is opposite the middle-length side: the smallest, largest, or middle-size angle?

- Do you think these relationships will always be true? Draw another triangle and see.
- What happens to the angle measures if two or three sides are congruent?
- What happens if one angle is a right angle?
