Question

Select all true statements

a
parallel lines meet at a point

b
The angle between parallel lines is 0

c
The angle between perpendicular lines is 90

d
perpendicular lines meet at two points

Answer 1

The true statements are:

- **b**: The angle between parallel lines is 0 (correct because parallel lines do not intersect, so the angle between them is considered to be 0).

- **c**: The angle between perpendicular lines is 90 (correct because by definition, perpendicular lines intersect at a right angle).

The false statements are:

- **a**: Parallel lines meet at a point (this is false, as parallel lines never intersect).

- **d**: Perpendicular lines meet at two points (this is false; perpendicular lines intersect at exactly one point).

So the true statements are **b** and **c**.
