Worked practice questions

Which of these has a fixed length because both its ends are fixed?

  1. A short ray
  2. A long line
  3. A flat plane
  4. A line segment
Show answer and solution

Correct answer: D. A line segment

1. A part of a line with two end points is a line segment. 2. A ray has just one end point. 3. A line has no end point and a plane is flat and spreads in two directions. _Source: Wikipedia, Line (geometry), Line segment_

Two rays that share an endpoint form what?

  1. An angle
  2. A triangle
  3. A circle
  4. Two lines
Show answer and solution

Correct answer: A. An angle

1. Two rays from the same endpoint open out from that point. 2. The shape they make is an angle. 3. A triangle needs three sides and a circle is a curve. _Source: Wikipedia, Line (geometry), Ray_

Three points that are not on one straight line lie in how many flat planes?

  1. Zero planes
  2. Exactly one
  3. Exactly two
  4. Infinitely many
Show answer and solution

Correct answer: B. Exactly one

1. Three points not in a line fix a flat surface. 2. Exactly one plane contains them, as with a three-legged stool that never wobbles. 3. Infinitely many planes pass through only two points. _Source: Wikipedia, Line (geometry), Collinear points_
