Module 2 Lesson 9-- Rotations

by Tiffany Weekly

​I can perform, explain, and identify rotations in

90 degree increments around the origin.

Multiple Choice

• a

• b

• c

• d

Rotations

• Rotation is a "TURN"s

• Rotations are considered RIGID because the pre-images and final images will always be CONGRUENT (Same Shape, Same Size, Same Measurements, Same Lengths)

Multiple Choice

How many quadrants are there on a coordinate plane?

• 1

• 2

• 3

• 4

Multiple Choice

Identify the quadrant where the point is located. (6 , 3)

• I

• II

• III

• IV

Multiple Choice

Identify the quadrant where the point is located. (-3 , -4)

• I

• II

• III

• IV

Multiple Choice

Identify the quadrant where the point is located. (10 , -5)

• I

• II

• III

• IV

Multiple Choice

I'm (-4, -1) and I moved clockwise 2 quadrants. Where am I?

• I

• II

• III

• v

Multiple Choice

I'm (-4, 5) and I moved counterclockwise 1 quadrant. Where am I?

• I

• II

• III

• v

Multiple Choice

How many degrees is a quadrant worth?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

Multiple Choice

The clock is going in the __________ direction.

• Clockwise

• Counterclockwise

Multiple Choice

Triangle A is rotated 270° clockwise with the origin as the center of rotation to create a new figure. Which triangle shows the new location?

• A

• B

• C

• D

Multiple Choice

What type of rotation does this represent (from red to blue)?

• 270⁰ clockwise

• 180⁰

• 90⁰ clockwise

Multiple Choice

How many degrees was the figure rotated?

• 90 degrees counterclockwise 
• 180 degrees
• 90 degrees clockwise

Multiple Choice

If you started with a pre-image in Q1, then rotated it $$90\degree$$  CCW (counterclockwise) around the origin. What quadrant would you graph your image?

• Q1

• Q2

• Q3

• Q4

Remember 90 (or 270) degree swap (x,y) abs. value.. We can always determine sign change using knowledge of quadrants!!!

Multiple Choice

Rotate the point (5,5) around the origin 180 degrees counterclockwise. State the image of the point.

• (5,-5)

• (5,5)

• (-5,5)

• (-5,-5)

Multiple Choice

Rotate the point (-5,8) around the origin 90 degrees clockwise. State the image of the point.

• (-8,5)

• (8,-5)

• (8,5)

• (5,-8)

Multiple Choice

Rotate the point (7,8) around the origin 90 degrees counter clockwise. State the image of the point.

• (-7,-8)

• (8,-7)

• (-8,7)

• (8,7)

Multiple Choice

If you were to rotate ABCD 90°clockwise about the origin, what would the coordinate of A' be?

• (-5, 5)

• (5, -3)

• (-5, 3)

• (-3, 3)

Multiple Choice

True or False: A rotation is Rigid Motion so it proves the shapes are congruent.

• True

• False

Open Ended

Remember to describe using EVERY characteristic of a Rotation.
