Determining Congruence
Drag the ruler and protractor over the sides and angles to
measure them.
Use the tool to explore the side lengths and angle
measures of the three triangles.
Select the triangles that are congruent. Check all that
apply.
triangle XYZ
triangle DEF
triangle ORP

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.
