Question 7

Gregory knows that triangle ABC is reflected onto triangle A'B'C'. Which statement about the figures is true?

Accepted Answer

If Gregory draws the segment with endpoints A and A', then the midpoint will lie on the line of reflection.

Answer

If Gregory draws the segment with endpoints B and C', then the midpoint will be on the line of reflection.

Answer

Points A and B are equidistant from the line of reflection.

Answer

Line segment AB will be perpendicular to the line of reflection.

Question 8

Answer

The triangles are reflected across the x-axis.

Answer

The triangles are reflected across the y-axis.

Answer

The triangles are reflected across the line y = -x.

Question 9

Accepted Answer

segment GH

Answer

segment AF

Answer

segment DC

Answer

segment JK

Question 10

Accepted Answer

x = 6

Answer

y = 6

Answer

y = x

Answer

y = 2

Question 14

What is the equation for the line of reflection?

Accepted Answer

y = x

Answer

x = 3

Answer

y = 3

Answer

x = 6

Question 15

Triangle PQR is reflected across a line, P = (4,-5), and P' = (-4,-5). What is the line of reflection?

Accepted Answer

the y-axis

Answer

the x-axis

Answer

the line y = x

Answer

the line y = -x

Question 16

Clayton needs to reflect the triangle below across the line y = x. Which statements about the reflection are true? Check all that apply.

Accepted Answer

Clayton could use the rule (y,x) to find the points of the image.

Accepted Answer

C' will remain in the same location as C because it is on the line of reflection.

Accepted Answer

The image and the pre-image will be congruent triangles.

Accepted Answer

The image and pre-image will not have the same orientation because reflections flip figures.

Answer

C' will move because all point move in a reflection.
