Similar and Congruent

Choose the correct scale factor:

• 2

• 3

• 1/3

• 1/2

Choose the correct transformations

• rotate 90 degrees counter-clockwise around the origin, and then reflect over the x-axis

• right 1, down 4, and then reflection over the y-axis

• right 6, and then reflection over the x-axis

• reflection over the line y=x, and then translate up 4, right 2

Rectangle ABCD is undergoing a series of transformations. Which of the following transformations will NOT cause the resulting rectangle to maintain congruence with rectangle ABCD?

• Translation 3 units left, then translation 7 units down.
  

• Dilation by a scale factor of 3, then dilation by a scale factor of 3.

• Dilation by a scale factor of 2, then dilation by a scale factor of 1/2.

• Translation 4 units right, then translation 6 units up. 

Which transformation(s) preserve congruency?

• rotations

• reflections

• translations

• dilations

Which rule shows a scale factor of 4?

• (x, y) → (y, x)

• (x, y) → (x + 4, y + 4)

• (x, y) → (x, -y)

• (x, y) → (4x, 4y)

Congruent geometric figures have the:

• Same size

• Sides Equal

• Same Size and Same Shape

• All Angles Equal

A dilation produces a similar figure

• True

• False

Are these figures similar?

• yes

• no

• i don't know

• not enough information

Matching sides are called

• Corresponding Sides

• Corresponding Angles

• The Same

• Congruent Sides

Name the postulate, if possible, that makes the triangles congruent.

• SAS

• ASA

• AAS

• Not Possible
