Dilations
Question 6 of 10 • SRC 2022 M/J Grade 8 Pre-Algebra Q1
Elijah was trying to determine whether one triangle is a dilation of the other. Which statements about his solution are true? Check all that apply.Elijah’s work: 3 is not a factor of 5, so it must be a relationship with addition. Therefore, the triangles are not proportional and cannot form a dilation.
Answer
A
Elijah did not know that scale factors can be fractions or decimals greater than zero.B
Elijah did not know that dilations are proportional and the relationships are multiplicative, not additive.C
Elijah should have compared the ratios to determine if they are equivalent.
D
Elijah needs to know which triangle is the pre-image and which triangle is the image in order to determine if they are proportional.E
Elijah needs labels on the points to determine which sides correspond when writing the ratios.
