In a trapezium, what property do one pair of opposite sides have?
Show answer
One pair of opposite sides are parallel.
Are the x-axis and y-axis parallel or perpendicular?
Show answer
Perpendicular. They meet at a right angle (90°).
If line AB is parallel to line CD, and line EF is perpendicular to AB, what is the relationship between EF and CD?
Show answer
EF is also perpendicular to CD. A line perpendicular to one of two parallel lines is perpendicular to both.
What symbol notation is used to mark parallel lines on a diagram?
Show answer
