Lesson 10: Practice Problems
Problem 1
Of the three lines in the graph, one has slope 1, one has slope 2, and one has slope
Problem 2
Draw three lines with slope 2, and three lines with slope
Problem 3
The figure shows two right triangles, each with its longest side on the same line.
Explain how you know the two triangles are similar.
How long is
? For each triangle, calculate (vertical side)
(horizontal side). What is the slope of the line? Explain how you know.
Problem 4 From Unit 2 Lesson 9
Triangle
Explain how you know that Triangle
is not similar to Triangle . Give possible side lengths for Triangle
so that it is similar to Triangle .
