Question 2

1)
\overline{PR} \perp \overline{QS},
\overline{PQ} \cong \overline{PS} (given)

2)
\overline{PR} \cong \overline{PR} (reflexive property)

3)
\angle PRQ and
\angle PRS are right angles (perpendicular lines form right angles)

4)
\triangle PRQ and
\triangle PRS are right triangles (a triangle with a right angle is a right triangle)

5)
\triangle PRQ \cong \triangle PRS (HL)

Question 3

1)
\angle C is a right angle,
\overline{AC} \cong \overline{AE},
\overline{DE} \perp \overline{AB} (given)

2)
\angle DEA is a right angle (perpendicular lines form right angles)

3)
\triangle ACD and
\triangle DAE are right triangles (a triangle with a right triangle is a right angle)

4)
\overline{AD} \cong \overline{AD} (reflexive property)

5)
\triangle ACD \cong \triangle AED (HL)

6)
\angle CAD \cong \angle DAE (CPCTC)

7)
\overline{AD} bisects
\angle BAC (if a segment splits an angle into two congruent parts, it is an angle bisector)
