Question 5 • SRC 2022 M/J Grade 8 Pre-Algebra Q1
Trapezoid is the image of trapezoid K after a series of transformations.Bella and Marco described the sequence of transformations in different ways.Bella’s SequenceMarco’s Sequence1. a dilation of trapezoid K by a scale factor of with the origin as the center of dilation2. a rotation of about the origin3. a translation of 1 unit down1. a reflection of trapezoid K across the x-axis2. a dilation by a scale factor of with the origin as the center of dilation3. a translation of 1 unit downWhich sequence or sequences are correct and why?
Answer
A
Only Bella is correct.B
Only Marco is correct.C
Both Bella and Marco are correct because both chose the correct scale factor for the dilation and both describe other transformations that could be used.D
Neither Bella nor Marco is correct because the scale factor they chose for the dilation is incorrect.
