Explain Slope with Similar Triangles

Use the triangles to help you identify the slope! Remember to simplify!

rise/run

• 2/3

• 3/4

• 3/2

• 1/3

Find the slope of the line.

• 1/2

• -1/2

• 2/1

• -2/1

What can you conclude about the triangles on the line shown on the graph?

• The triangles are congruent and therefore have the same slope.

• The triangles are similar and therefore have the same slope.

• The triangles are similar but do not have the same slope.

• The triangles are unrelated to one another.

Triangles ABC and DEF are similar. The slope of triangle ABC is...

• which is the same as the slope of triangle DEF.

• 3/4 which is the slope of hypotenuse of triangle DEF.

• 4/3 which is the slope of triangle DEF.

• -1 which is the same as the slope of triangle DEF.

Triangles ABC and DEF are similar. The slope of the hypotenuse of ABC is...

• the same as the hypotenuse of triangle DEF

• half of the slope of triangle DEF

• twice the slope of the hypotenuse of DEF

When given two similar triangles on the same line, they will ALWAYS have the same _______________?

• y-intercept

• x

• slope

• y

Which shows a proportion comparing the rise and run for each of the similar slope triangles, and the numeric value?

• Choice A

• Choice B

• Choice C

• Choice D
