Question

1. esperalda 6. △spm≅△sqm 6. sss congruence theorem any point on a bisector of 7. a line segment is equidistant from the two endpoints of the line segment. corresponding parts of 7. congruent triangles are congruent which statement best describes jamies proof? a jamie made his first mistake in step 3. he cannot conclude that mp is congruent to mq based on the fact that line ms is a bisector of pq. b jamie made his first mistake in step 5. he used the statement he was trying to prove as a reason. c jamie made his first mistake in step 6. the congruence statement should be that △spm is congruent to △qsm. d jamie did not make any errors in his proof.

Explanation:

To prove that any point on a bisector of a line - segment is equidistant from the two endpoints of the line - segment, you cannot use the statement you are trying to prove as a reason. In a proof, the reasons should be previously established postulates, theorems, or definitions. Here, if Jamie used the statement he was trying to prove as a reason in Step 5, it is a logical error.

Answer:

B. Jamie made his first mistake in Step 5. He used the statement he was trying to prove as a reason.
