Answer 1

Answer:

16. AB is parallel to DC and AD is parallel to BC.

Step-by-step explanation:

15. In parallel lines, corresponding angles are equal.

As angle 1 = 90° (given),

and angle 1 = angle 2 (corresponding angles)

Angle 1 = Angle 2 = 90°

Thus, when a line is perpendicular to one of two parallel lines, it is also perpendicular to the second line.

16. Co - interior angles in parallel lines have a sum of 180°.

As 115° + 65° = 180°,

AB is parallel to DC and AD is parallel to BC.
