Midterm Review Key The slopes of perpendicular lines are negative
... 24. If you plot the point (-3, -1) and rotate the paper 180 degrees, counterclockwise, you will see that the image of the point will now be at (3, 1). Choice 1 is correct. (Alternatively, you can use the rule (x, y) → (-x, -y) for a rotation of 180 degrees). 25. Translations are achieved by adding ...

... seen by the medium triangle with sides 9 m, 18 m, and 18 m. The triangles are all similar because each smaller triangle is nested in the larger triangle. Note the base of each triangle is half the length of its legs. The large isosceles triangle has a leg of 30 m, so its base is 15 m. Also, the ...
