This symbol does NOT mean
“Triangle” in this case. It is the
Greek letter “Delta.”
It is used to represent change.
In this case, “change” means the
change in y over the change in

Slope Ratios and Angles
In Lesson 4.1.1, you discovered that certain slope angles
produce slope triangles with special ratios. Below are the
triangles you have studied so far. Note that the angles
below are rounded to the nearest degree.
