Congruent by Transformations

Write a rule for the translation.

Describe the transformation shown in the picture.

• Reflection about the x-axis

• Reflection about the origin

• Rotation by 270 degrees about the origin

• Rotation by 90 degress about the origin

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

Identify the transformation.

• Reflection about y-axis

• Reflection about x-axis

• Rotation about the origin by 180 degrees

• Translation 6 units down

Which best describes the accuracy of the congruency statements?

• Jason’s statement is correct. RST is the same orientation, shape, and size as ABC.

• Both statements could be correct. RST could be the result of two translations of ABC. TSR could be the result of a rotation and a translation of ABC.

• Both statements could be correct. RST could be the result of two translations of ABC. TSR could be the result of a reflection and a translation of ABC.

• Kelley’s statement is correct. TSR is the same orientation, shape, and size as ABC.

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C?

• Each triangle is a right triangle.

• Each triangle is an isosceles triangle.

What transformation does NOT preserve congruence?

• dilation

• rotation

• reflection

• translation

Which statement is true about the transformation?

• The transformation preserves congruency and maintains orientation.

• The transformation preserves congruency and does not maintains orientation.

• The transformation does not preserves congruency but maintains orientation.

• The transformation does not preserves congruency or maintains orientation.

Which statement is true about the transformation?
