  29. At what angle measure am I holding the sai in my right hand? 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.

  36. SWBAT: 1) Determine slope ratios for given s. 2) Solve for missing side lengths on s using slope ratios. Today’s Objective: *SWBAT= Student Will Be Able To

  37. 1) What is the slope ratio for the given ? ____ 4-23 10 7 = 1.429 2) How can we solve for x? TTW: 1) Demonstrate using Dynamic Geometry Tool 2) H/O RP 4.1.3

  38. Slope ratio = ____ Slope ratio = ____ Proportion Proportion __ __ __ __ = = 4-24

  39. Slope ratio = ____ Slope ratio = ____ Proportion Proportion __ __ __ __ = = 4-24

  40. Slope ratio = ____ Proportion Proportion __ __ __ __ = = Slope ratio = ____ 4-24

  41. Slope ratio = ____ Proportion __ __ = A side length of a  can not be 0! Neither can an ! 4-24

  42. Slope ratio = ____ Proportion __ __ = You can’t have 2 90 s in a ! 4-24

  43. 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.
