Quiz

Test your knowledge of vertical and horizontal lines in this quiz.

Learn

We see lines everywhere around us all the time, for example on buildings, books, televisions, photo frames, roads etc.

Did you know that different types of lines have different names?

Types of lines

  • A vertical line goes up and down.

  • A horizontal line goes left to right.

Why not have a look around and see if you can find any horizontal and vertical lines?

Now have a look at the pencils below. Can you count how many vertical and horizontal pencils there are?

How many did you find? You can see that there are 4 vertical pencils and 4 horizontal pencils.

Now watch this video to find out how to recognise parallel lines and perpendicular lines.

Practise

Activity 1

Parallel names

Write your name in capital letters, like in the example below.

  • How many pairs of parallel lines can you find?
  • How many pairs of perpendicular lines?

  • Which capital letter has the most parallel lines in it?

  • Which capital letter has the most perpendicular lines in it?

Activity 2

House of lines

This is a two-player game.

Pick a room in your house!

Player 1 gets a point for every pair of parallel lines they can find in the room.

Player 2 gets a point for every pair of perpendicular lines they can find.

The player with the most points wins!
