5.6 Comparing Angles and Sides in Triangles


Here you’ll learn how to compare sides and angles in triangles. Specifically, you’ll learn how to order the angles of
a triangle from largest to smallest based on the length of their opposite sides.


What if two mountain bikers leave from the same parking lot and head in opposite directions on two different trails?
The first rider goes 8 miles due west, then rides due south for 15 miles. The second rider goes 6 miles due east,
then changes direction and rides 20◦east of due north for 17 miles. Both riders have been traveling for 23 miles, but
which one is further from the parking lot? After completing this Concept, you will be able to compare triangles in
order to answer questions like this one.
