Question

In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving that triangle RST is congruent to triangle RSQ given that RS ⊥ ST, RS ⊥ SQ, and ∠STR ≅ ∠SQR.

Answer 1

1)
`\overline{RS} \perp \overline{ST}, \overline{RS} \perp \overline{SQ}, \angle STR \cong \angle SQR` (given)

2)
`\overline{RS} \cong \overline{RS}` (reflexive property)

3)
`\angle RST` and
`\angle RSQ` are right angles (perpendicular lines form right angles)

4)
`\triangle RST \cong \triangle RSQ` (AAS)
