What are parallel lines?
Straight lines.
Lines that meet each other.
Lines that never meet.
Virtual lines.
The figure shows that l1 is parallel to l2 and l3 is a transversal. The angle marked x measures:
50o.
130o.
150o.
100o.
A line joining two endpoints is called:
Parallel lines.
Line segment.
Intersecting lines.
A ray.
What are perpendicular lines?
All are correct.
Lines that intersect to form a right angle at the point of intersection.
Lines that will cut other lines (usually parallel lines) at an angle other than right angle.
None is correct.
Given the lines
Lā: y = -3x + 3 and
Lā: y = mx - 2 such that L, is parallel to Lā, the value of m is:
-3.
