A triangle has an angle measuring 90 degrees, and angle measuring 20 degrees, and a side that is 6 centimeters long. The 6 centimeter side is between the 90 degree and 20 degree angles. How many triangles can be drawn like this? Group of answer choices 2 1 99 0

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.
