How it works
A ray has one end point. A line segment has two. A line goes on forever both ways.
Parallel lines never meet. Perpendicular lines meet at a square corner.
A square has two pairs of parallel sides.
Worked examples
A ray
- A ray starts at point M and goes on through N.
- It has one end point.
- A ray has 1 end point.
Pairs in a square
- The top and bottom of a square never meet. The left and right never meet.
- That is 2 pairs.
- A square has 2 pairs of parallel sides.
A trapezoid
- Only the top and bottom of a trapezoid are parallel.
- The slanted sides would meet.
- A trapezoid has 1 pair.
A taste of the worksheet
These are the first problems of set A. The printable sheet has many more, with an answer key.
- The drawing stops at point A and stops at point B. What is it called?
- A line goes on and on in both directions, so it has no end points.
- A ray has two end points.
- Which angle is a right angle?
- Is this angle acute, right or obtuse?
