Thalia did not have a tool to help her find the slope angle in the triangle below. However, she claims that the slope angle has to be more than
. Do you agree with Thalia? Why?
An isosceles right triangle has a slope of
and slope angle of . Does this triangle have a larger or smaller ratio? What does this tell us about the slope angle?
Yes, because the slope ratio is greater than
, the angle must be greater than .
Lyra was trying to find the slope ratio for the triangle below, and she says the answer is
. Isiah claims that cannot be correct. Who is right? How do you know?
Use the same method as in part (a).
Without finding the actual value, what information do you know about
in the diagram below?
