Rotation and Dilation Quiz

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

• reflection
• translation
• rotation
• dilation

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

• 270⁰ clockwise
• 360⁰
• 90⁰ counterclockwise
• 180⁰

Translations, reflections and rotations are all known as ________________________.

• Geometry
• Rigid Transformations
• Congruent
• Non- Rigid Transformations

Which transformation is NOT a rigid motion (the size changes)?

• reflection
• rotation
• dilation
• translation

If (3,2)→(-3,-2) represents a counterclockwise rotation of the point on a coordinate plane, how many degrees is the rotation?

• 90

• 180

• 270

• 360

If you were to rotate ABCD 180°  about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, -5)
• (-5, 3)
• (-3, 3)

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

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

If I rotate a trapezoid
90⁰ clockwise,
and its in quadrant III (3),
which quadrant would it move to?

• Quadrant 1 (I)
• Quadrant 2 (II)
• Quadrant 3 (III)
• Quadrant 4 (IV)
