    Explain why ∆ACB is similar to ∆DFE and deduce that AB has the
    same slope as BE . Choose the BEST answer
A) ABC is similar to DFE because they are both triangles
B) ABC is similar to DFE because they both are graphed on a line
C) ABC is similar to DFE because they both share a proportional slope.

    What can be concluded by these two triangles?
A) They show that the two triangles are congruent because they share the same slope which is 3/2
B) The triangles show different slopes, therefore they are not similar triangles
C) Triangle A represents a positive slope and triangle B represents a negative slope.
D) The triangles do not describe the slope.

A) Fred's claim is incorrect because the ratio of the height to the base of Fred's triangle is 2/4 . Jenny's triangle has a ratio of the height to the base of 3/6. These ratios are equivalent.
B) Fred's claim is correct because the triangles are 2 different sizes.
C) Fred's claim is incorrect because Fred's slope is greater than Jenny's slope.
D) Fred's claim is correct because the triangles are on opposite sides of the line. So, one slope is less than the other.
