You will need today’s Resource Pages and class work for Lesson 4.1.2. Please store your work in a safe location at the end of this lesson.
4-2d.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 x – Or, in other words distance.

Today’s Objective:
SWBAT connect specific slope ratios to their related s & use this information to find missing sides or s of right s with 11°, 22°, 18°, or 45°s.
*SWBAT = Student Will Be Able To
Slope Ratios and AnglesIn 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.
At what angle measure am I holding the sai in my right hand?
Today’s Objective:
SWBAT:1) Determine slope ratios for given s.2) Solve for missing side lengths on s
using slope ratios.
*SWBAT = Student Will Be Able To

= 1.429
2) How can we solve for x?
4-26
8 min.
1) What happens to the slope ratio when the angle increases? Decreases?
2) What happens to the slope ratio when the angle is 0°? 90°?
3) When is a slope ratio more than 1? When is it less than 1?
4-26
8 min.
1) What happens to the slope ratio when the angle increases? Decreases?
2) What happens to the slope ratio when the angle is 0°? 90°?
3) When is a slope ratio more than 1? When is it less than 1?
Today’s Objective:
SWBAT:1) Use a scientific calculator to find a
slope ratio. (Tangent ratio.)2) Identify rise & run when the is not
oriented as a slope triangle.
*SWBAT = Student Will Be Able To
