Part A Identify a sequence of transformations that will show that trapezoid 1 must be congruent to trapezoid 2.

Explain why the trapezoids must be congruent.

Part B

A dilation, with center of dilation at the origin, will be performed on trapezoid 1 to create trapezoid 3, which is not shown.

Explain why trapezoid 3 must be similar to trapezoid 1, even though the scale factor is unknown.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
