Guidance on Solving Exercise 3 on Page 51 of Mathematics 4 textbook
Solving method:
- Parallel lines are two lines lying on the same plane without intersecting.
- Lines are perpendicular if the angle between them is 90 degrees.
Answers:
a) MN is parallel to QP (Figure MNPQ).
DI is parallel to GH (Figure DEGHI)
b) NM is perpendicular to MQ (Figure MNPQ)
DE is perpendicular to EG (Figure DEGHI)
DI is perpendicular to IH (Figure DEGHI)
IH is perpendicular to GH (Figure DEGHI).
