Describing Effects of Transformations

What would the coordinates be for Q(4,1) after a translation 3 units left and 4 units down, then a reflection over the x-axis?

• (1, -3)

• (-1, -3)

• (1, 3)

• (-1, 3)

Point (-5,2) is reflected over the y axis and the rotate 180 about the origin. Where is the new point located?

• (5,2)

• (-5,-2)

• (-5,2)

• (5,-2)

Which of the following is a similarity transformation?

Warm up: Which figure can be transformed into figure P by a translation 2 units to the right followed by a reflection across the x-axis

?

• Figure J

• Figure K

• Figure L

Identify the transformations:

• translation and rotation

• rotation and reflection

• translation and dilation

• two translations

Harper completed a transformation of pre-image ABCD that results in the image A’B’C’D’ as shown. Which statements about the relationship between the pre-image and the image can Josh concluded are true?

• The image is both congruent and similar to the preimage because all congruent figures are also similar figures.

• The image is NOT congruent to the preimage because rotations change the length of the line segments and angle measures.

• The image is similar to the preimage because the corresponding sides have a ratio of 1:1.

• The image is NOT similar to the preimage because the areas of the figures are equal.

• The image is congruent to the preimage because the image is the result of a rotation.

Quadrilateral RSTU is reflected across the y-axis AND translated down 3 units. Which coordinates best represent S’ ?

• (-3, -9)

• (-1, -7)

• (1, -7)

Identify the transformation:
