Unit 1 Review Activity 9/29/23

Name the 2 pairs of congruent angles and 2 pairs of supplementary angles.

• Congruent: QSR and RSU

  Supplementary: QST and RSU

• Congruent: QST and RSU

  Supplementary: QSR and RSU

• Congruent: TSU and RSU

  Supplementary: QSR and RSQ

Which of these sequences of transformations would return a shape to its original position?

• A. Reflecting over the x-axis, then reflecting over the y-axis

• B. Rotating 90 degrees clockwise around a point, then rotating another 90 degrees

• C. Translating 5 units up and 3 units to the right, then translating 3 units to the left and 5 units down

• D. Translating 3 units to the right then reflecting over the x-axis

Which quadrant will this triangle be in after a reflection across the x axis?

• Quadrant 1

• Quadrant 2

• Quadrant 3

• Quadrant 4

What are the coordinates of B' after a reflection across the x axis? (Be sure to use parenthesis and no spaces in your answers)

How could you prove that these polygons are congruent?

• Rotate the figure 180 degrees, then translate it down 5 spaces.

• Reflect the original figure of a line, then dilate the figure.

• The Figure will not be congruent because it is corresponding.

• See if corresponding angles and portions are congruent and the shape. We could measure the figure or use trace paper to do this.

Find the value of X.

• 91

• 89

• 81

• 180

What's the value of x?

• 360 degrees

• 180 degrees

• 124 degrees

• 56 degrees.

What is the measure of the angle that is adjacent to x (adjacent to x means beside x)?

• 180 degrees

• 123 degrees

• 124 degrees

• 56 degrees

What is the measure of angel x? ( Enter numbers only)

Which angle is congruent to angle BCA?

• Angle BAF

• Angle DAF

• Angle FAE

• 109 degrees
