Q. Consider the figure. Which reason can be used to justify Step 5 ?Given: QR≅QT; S is the midpoint of RT.Prove: △QRS≅△QTS\begin{tabular}{|l|l|}\hline \multicolumn{1}{|c|}{ Statements } & \multicolumn{1}{c|}{ Reasons } \\\hline 1.

Given Information and Proof: Look at the given information and what needs to be proved.Given: QR≅QT and S is the midpoint of RT.Prove: ∠QRS≅∠QTS
Reason for Statement 3: Identify the reason for statement 3.Since S is the midpoint of RT, by definition of midpoint, TS≅SR.Reason for statement 3: Midpoint Theorem.
Reason for Statement 4: Identify the reason for statement 4. QS is the same segment as SQ, so they are congruent by definition. Reason for statement 4: Reflexive Property.
Reason for Statement 5: Determine the reason for statement 5.We have two pairs of congruent sides and a pair of congruent angles not included between them.Reason for statement 5: This should be AAS (Angle-Angle-Side) congruence criterion, but let's check the options.
Checking Options: Check the options against the information we have.A) Midpoint Theorem - Already used for statement 3.B) AAS - Seems correct as we have two angles and a non-included side congruent.C) SSS - We don't have three sides congruent.D) Reflexive Property - Already used for statement 4.The correct answer is B) AAS.
