Maths in rugby: conversion angles

Quick answer

In rugby, the angle to the goal posts changes depending on where you kick from. The closer you are to the goal line, the wider the angle to the posts, making it easier to score a conversion.

Learning outcome

By the end of this page, you will understand how changing your position affects the angle to the goal posts when kicking for a conversion in rugby, and you will be able to compare angles to decide the best kicking position.

• You can draw a simple diagram showing how position changes the angle to the goal posts
• You can explain why being closer to the goal line helps when kicking for a conversion
• You can use real-world examples to compare angles
• You can predict the best place to kick from based on angle size

Why this matters

Understanding angles helps rugby players make smart decisions during a game. When a team scores a try, they get a chance to kick for a conversion. The angle to the goal posts changes depending on where the kick is taken from. A wider angle makes it easier to score. This is why rugby players and coaches think carefully about where to kick from. You use angles like this in many other activities too – like aiming a water pistol, throwing a ball to a friend, or even playing a game of football!

How it works

When you're kicking for a conversion in rugby, imagine you are standing in front of the goal posts. The angle to the goal posts is the space between the two posts as seen from where you are standing. If you're standing very close to the goal line, the angle is wide. If you're standing far away, the angle is narrow. This is because:

1. Imagine two lines going from your feet to the left and right goal posts
2. These lines make an angle
3. When you move closer to the posts, the lines get further apart (wider angle)
4. When you move further away from the posts, the lines get closer together (narrower angle)

Think of it like looking at a wide gate versus a narrow gate. The wide gate looks bigger from close up, and the narrow gate looks smaller from far away.

Examples you can see

Let’s look at a simple example using a rugby pitch. Imagine the goal posts are 5.6 metres apart. Here are some positions and the angles they create:

Notice how the angle gets smaller the further you move away from the goal line. This makes kicking harder.

Try it as a mini adventure

Rugby Angle Quest

Imagine you're a rugby player who just scored a try. You get to kick for a conversion. You can choose where to stand to kick from. Here's your mission:

1. Draw a rugby pitch on paper or the floor with tape
2. Mark the goal posts 5.6 metres apart
3. Place a marker 2 metres from the goal line
4. Place another marker 8 metres from the goal line
5. Place a third marker 15 metres from the goal line
6. From each marker, draw lines to the left and right goal posts
7. Look at the angles and decide which one is the easiest to kick through

Which position gives you the biggest angle? That's where you should stand to kick!

Common mistakes

• Mistake: Thinking that standing further away from the goal line is better because it’s easier to see the goal posts.
• Why it happens: Children often think that seeing more is better, but in rugby, the angle matters more than how far you can see.
• Fix: Remember, a wide angle is easier to kick through than a narrow one.
• Mistake: Not realising that the angle changes as you move side to side.
• Why it happens: When you move left or right, you change the angle even if you stay the same distance from the goal line.
• Fix: Try moving side to side while keeping the same distance from the goal line to see how the angle changes.
• Mistake: Believing that the angle is the same no matter where you kick from.
• Why it happens: Children may not understand that the angle depends on the position, not just the distance.
• Fix: Use a ruler or pencil to draw lines from different positions to the goal posts and measure the angles.

Parent and carer guide

Helping your child understand this concept can be fun and simple:

1. Use a piece of paper or the floor to draw a simple rugby goal line and posts
2. Have your child place a marker (like a toy or coin) at different distances from the posts
3. Draw lines from the marker to each post to show the angle
4. Ask your child to compare the angles and decide which one is the easiest to kick through
5. Use everyday examples like looking through a narrow gate versus a wide gate to explain the concept
6. Don’t worry if your child gets confused at first – it's normal to think about angles differently at first
7. Reinforce that the wider the angle, the easier it is to score
8. Encourage them to draw or act out different positions to understand the idea
9. Keep it playful and don’t make it feel like a test
10. Ask questions like: “Which position looks easier to score from?” or “Why do you think that angle is bigger?”

Practice questions

1. What happens to the angle to the goal posts when you move closer to the goal line?
2. Which position gives you the biggest angle – 3 metres from the goal line or 10 metres from the goal line?
3. If you're standing 5 metres from the goal line, what do you notice about the angle compared to standing 15 metres away?
4. Why do rugby players often choose to kick from close to the goal line?
5. Draw a simple rugby pitch with 3 kick positions and show the angles for each one.

Answers:

1. The angle gets wider
2. 3 metres from the goal line gives the bigger angle
3. The angle is wider when you're closer (5 metres)
4. Because a wider angle makes it easier to score
5. Draw lines from 3 positions to show wider and narrower angles

FAQ

Why is the angle important in rugby?

The angle to the goal posts determines how easy or hard it is to score a conversion. A wider angle makes it easier to kick through the posts.

Can you change the angle by moving side to side?

Yes! Moving left or right changes the angle even if you stay the same distance from the goal line.

Is the angle the same for everyone in rugby?

No, the angle changes depending on where each player stands. Each player must choose the best position to get the widest angle.

How can I practice this at home?

You can draw a rugby goal line and mark different positions. Then draw lines to the goal posts to see how the angle changes.

What other games use angles like this?

Many games use angles, like football, basketball, or even aiming a water pistol. The wider the angle, the easier it is to score or hit your target.
