Question 4

Which graph shows the image of the triangle reflected across the line of reflection shown?

Revolt · Accepted Answer

On a coordinate plane, a triangle has points (2, 2), (4, 4), (9, 0).

Question 5

Which statement correctly identifies the line of reflection?

Revolt · Accepted Answer

The triangles are reflected across the line y = x.

Question 6

Gregory knows that is reflected onto . Which statement about the figures is true?

Revolt · Accepted Answer

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

Question 7

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

Revolt · Accepted Answer

the y-axis

Question 8

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

Revolt · Accepted Answer

Clayton could use the relationship to find the points of the image.; C’ will remain in the same location as C because it is on the line of reflection.; The image and the pre-image will be congruent triangles.; The image and pre-image will not have the same orientation because reflections flip figures.
