Drawing Angles with a Protractor

Learn to draw angles of a given size accurately using a protractor and ruler. You'll mark the centre dot first, rule the baseline, then count round the scale to place the second ray.

Warning: Your screen size is quite small for viewing this. Rotate your device into landscape mode if you can.

Your turn

Your teacher is running this lesson on the board. Here is the part you can try yourself.

Your written work is on page 77

Angle tool

1 - Getting Started ~4 mins

Illustration for Getting Started You already know how to measure an angle that is already drawn on the page. Today the job flips: I will give you a size, and you draw the angle to match.

Key point

Watch the screen. I am going to draw a 60° angle in three moves. Before I start, tell me: which do you think comes first, the dot in the middle or the slanted line?

👇 Mark your steps as done as you complete them.

2 - Watch and Notice ~9 mins

Each angle was drawn in three moves: mark the dot, rule the baseline, then count round to the target and mark it, and rule the second ray through that mark. Here are four angles drawn to a target: 60°, then 95°, then 135°, then a tricky 175° that is almost a straight line. For each one, look at where the ray lands against the scale.

The 175° one is the one to watch: the ray is nearly flat, so a tiny slip changes the reading a lot.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~9 mins

Key point

Say the target aloud together before anyone drags the ray.

Today we draw these angles together on the board: 110°, then 75°, then 90°. The whole class calls out the size and predicts where the ray has to land, then a volunteer comes up to set it on the board.

4 - Draw the Angles in Your Copy ~3 mins

COPYBOOK MOMENT

Now you draw them yourself. In your maths copy, use your protractor to draw each of these angles and label it with its size underneath:

30°
75°
90°
115°
165°

When you finish, circle the one you found hardest to draw.

+10 XP

5 - Class Challenge ~7 mins

Key point

Now we practise to the target on the board. We work through these in order: 40°, then 125°, then 90°, and finally 160°. Set the ray, then use Check to confirm each one before we move on.

Draw to the target: Check each one
