Look at the figure shown below.

Triangle SQR is an obtuse angled triangle. Side SQ of the triangle is extended till T so that SQ is equal to QT. P is a point above point R. Points Q and P and points Q and R are joined using straight lines. Angle PQS is equal to angle TQR. Angle QSR is equal to angle QTP.

A student made the table shown below to prove that PQ is equal to RQ.

Answer 1

Provide the missing statement and justification in the proof.
Using complete sentences, explain why the proof would not work without the missing step.

Answer 2

look at the statement right after the blank statement, there the student was using CPCTC right ? wat does that tell us ?

Answer 5

yep ! that tells us, there must be some 'triangle congruence' statement in the blank

Answer 6

look at the previous statements, its easy to make out wat triangles are congruent :) give it a try
