Translations

100

A translation is when you do this to a figure.

What is L'(6,-1), M'(12,0), N'(9,5)?

Reflections

100

A reflection is when you do this to a figure.

What is flip it or make a mirror image of it?

200

Find the new coordinates of (3,-2) after you reflect the point over the x-axis.

What is (-3,-2)?

300

Write the notation of point (x,y) after it is reflected over the y-axis.

What is (-x,y)?

400

A picture with one point (-3,4) was reflected over the line y=x. What should be the new coordinates of the point?

What is (4,-3)?

500

What is D'(5,5), E'(8,5), F'(8,8), G'(5,8)?

Rotations

100

A rotation is when you do this to a figure.

What is spin it?

200

Find the new coordinates of (5,4) after you rotate the point with 180º.

What is (4,5)?

300

Write the notation of point (x,y) after it rotates 90º clockwise.

What is (y,-x)?

400

Figure QRST has vertices Q(2,-1), R (6,-1), S(6,-3) and T(2,-3). Which will be the coordinates of vertex R after the rectangle is rotated 90º counterclockwise about the origin?

What is (1,6)?

500

Properties

100

These three types of rigid transformations.

What are translations, reflections, and rotations?

200

Which transformation does not result in a congruent figure?

What is a dilation or distortion?

300

The properties of translations.

What are congruent and parallel (same slope) lines?

400

The properties of a reflection.

What is the LOR (1) bisects the corresponding points' line segments at a (2) right angle?

500

The steps to finding the point of rotation. 

What is (1) find the slope of the line connecting the corresponding vertices, (2) find the midpoints of the line, (3) draw a perpendicular line through the midpoints, and (4) the lines that overlap at the same point are is the POR?
