Answer:
Q1
- The opposite sides are two pairs of parallel lines.
- WY is transversal
- Angles 1 and 3 are congruent as alternate interior angles, same applies to angles 2 and 4.
- WY is the shared side and congruent to itself.
So we have two angles and the included side congruent to corresponding parts of the other triangle.
- 1≅3, 2≅4, WY≅WY
- ΔWXY ≅ ΔYZW
This is called angle-side-angle or ASA
