(01.02 MC) Dan uses a compass to draw an arc from Q as shown. He wants to construct a line segment through R that makes the same angle with as , as shown below: Which figure shows the next step to construct a congruent angle at R?

(03.05, 03.06 MC) Look at the figure shown below: Dora is writing statements as shown below to prove that if segment ST is parallel to segment RQ, then x = 12:   Statement Reason 1. Segment ST is parallel to segment QR. Given 2. Angle QRT is congruent to angle STP. Corresponding angles formed by parallel lines and their transversal are congruent. 3. Angle SPT is congruent to angle QPR. Reflexive property of angles 4. Triangle SPT is similar to triangle QPR. Angle-Angle Similarity Postulate 5. ? Corresponding sides of similar triangles are in proportion. Which equation can she use as statement 5?
