Practice with Beginning Congruent Triangle Proofs
Directions: When attempting to prove triangles congruent, it is important to satisfy all of the conditions of the congruent triangle method you are using. This activity is designed to help you organize your thinking about how the parts of a congruent triangle proof will come together. In each problem below, examine the diagram and the GIVEN information. You may wish to draw the diagrams on paper so that you can mark off the information.
-
Determine the method needed to prove the triangles congruent.
(ASA, SAS, AAS, SSS, or HL for right triangles only) -
Check to see if you have the correct method by looking at the Method for Congruent Triangles box at the bottom of the chart.
-
Each of the three components needed to support the chosen method appear to the left of their corresponding Statement.
-
Decide what Reasons can be used to support your decisions.
