Lesson 3 Summary

 

In this lesson you took an in-depth look at the meaning of slope. You saw how slopes relate to the steepness of slides, roofs, roads, and ramps. You also saw that considering the slope of objects is an important safety concern. In some cases, slope can make the difference between having or not having an accessible building.

 

You used a variety of different means to calculate and discuss slope. The formula percentage grade = × 100% was used to describe the slope of roads and ramps. You also applied the ratio form of a slope to discuss slope in terms of roof pitch. You then used your knowledge of slope to determine which of several objects was steeper.

 

In Section 2 you will explore slope further, but not in terms of a physical object as you did in this section. You will see that slopes can also describe a rate of change.
