3.maurice is cutting out shapes for a class project. he has a scrap of green poster board in the shape of a triangle, shown below. he wants to trim the large green triangle into a smaller triangle by cutting along the dotted line shown. if the red segment along the left side of the triangle measures 45 cm and the blue segment along the bottom of the triangle measures 81 cm, what is the length of poster board that maurice cut? *

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.
