Which answer choices correctly describe the rotation that maps figure ABCD to figure A
′B′C′D′? - answerA 90∘ counterclockwise rotation about the origin.
A 270∘ clockwise rotation about the origin.

Which statements are true about the transformation that maps triangle ABC to triangle A
′B′C′? - answerThe transformation preserves side lengths and angle measures.
The transformation is a rigid transformation.
Triangle A′B′C′ is the result of a reflection.
(6.1) Draw a line. Now draw a line perpendicular to the first line that passes through
point G (which is not at the intersection). Measure the distance of G from the first line.
Draw another point on the second line that is the same distance as G, but is on the
opposite side of the first line.
If G is the preimage, and the second point is the image, what transformation does this
show? - answerReflection.

, The transformation takes each point (x,y) to a new coordinate (x′,y′).
Which function correctly describes the transformation? - answer(x,y)↦(−x,y)
(6.2) The following transformation maps △ABC to △A′B′C′.
(x,y)↦(x−4,y+1)
Which answer correctly describes the transformation applied to △ABC? -
answer△ABC is moved 4 units left and 1 unit up to create △A′B′C′.
(6.2) Select two of the following mapping statements that are the result of the same
translation. - answer(−1,2)↦(2,−3)
(2,−3)↦(5,−8)
(6.3) In the following graph, trapezoid ABCD is transformed by a reflection in the y-axis
followed by a rotation 180∘ clockwise about the origin to obtain trapezoid A′B′C′D′.
Which answer correctly shows the image, trapezoid A′B′C′D′? -

Which series of transformations correctly maps parallelogram ABCD to parallelogram A
′B′C′D′? - answerA rotation 90∘ clockwise about the origin, followed by a translation 3
units down.
(06) Draw a line segment with endpoints M and R. Now draw a parallel line segment
that is the same length as MR line with the endpoints M′ and R′ in the same order.
Which answer correctly describes the transformation from MR line to M′R′ line? -
answerA translation.

Triangle ABC is reflected over line l to result in the image, triangle A′B′C′.
Which statements are true about the transformation that maps triangle ABC to triangle A
′B′C′? - answerThe angle measures remain the same from the preimage to the image.
The transformation is a rigid transformation.
The side lengths remain the same from the preimage to the image.

Which answer correctly describes the transformation from the preimage to the image? -
answerA translation 10 units left and 8 units down.
