What is geometry?
Geometry is the part of maths about points, lines, angles and shapes. When two rays start from the same point, they make an angle. We measure angles in degrees (°), and a right angle is 90°.
Think of a train 🚂 on its track: the straight rails are like parallel lines, the turns make angles and the round wheels are circles!
Kinds of angles
| Angle | Size | Example |
|---|---|---|
| 🔻 Acute | less than 90° | clock at 2 o'clock |
| 📐 Right | exactly 90° | corner of a book |
| 🔷 Obtuse | 90° to 180° | clock at 4 o'clock |
| 📏 Straight | exactly 180° | clock at 6 o'clock |
How to name an angle
- Hold the corner of a book on the angle.
- If it fits exactly, it is a right angle.
- If it is smaller, it is acute; if it is bigger, it is obtuse.
- If the arms make a straight line, it is a straight angle.

Maths Geometry Class 4
Geometry is the part of maths that studies points, lines, angles and shapes. In Class 4, children learn about line segments, rays and lines, the kinds of angles (acute, right, obtuse and straight), the parts of a circle (centre, radius and diameter), flat shapes like triangles and quadrilaterals, symmetry and the perimeter of simple shapes. This guide explains each idea in simple language for Class 4 students, parents and teachers. It goes with the Geometry worksheet for Class 4 on WitKnowLearn, which also gives an online quiz, online activities and interactive games on the same page.
Introduction to Class 4 Maths: Geometry
Subject: Maths, Class 4. Topic: Geometry: lines, angles, circles and shapes. This page is built around the learning goals schools test for the topic in any board; it is not a copy of a single textbook chapter.
What is there in this topic
- Point, line segment, ray and line
- Parallel and crossing lines
- Kinds of angles: acute, right, obtuse and straight
- Parts of a circle: centre, radius and diameter
- Triangles, quadrilaterals and other polygons
- Symmetry and the perimeter of simple shapes
Learning objectives
These objectives are written for this page from the topic's goals; they are not copied from any one book.
- Tell a line segment, a ray and a line apart.
- Name and compare angles using a right angle.
- Use the link between the radius and the diameter of a circle.
- Name shapes by their sides and find their perimeter.
Learning outcomes
After this page a child can:
- Say that a line segment has 2 end points and a ray has 1.
- Sort 45°, 90°, 150° and 180° into acute, right, obtuse and straight.
- Find the diameter of a circle with a radius of 7 cm (14 cm).
- Find the perimeter of a rectangle 8 cm by 3 cm (22 cm).

Line segment, ray and line
| Figure | End points | Can we measure it? | Example |
|---|---|---|---|
| Line segment | 2 | Yes | Edge of a ruler |
| Ray | 1 | No | Light from a torch |
| Line | None | No | Goes on forever both ways |
Kinds of angles
| Angle | Size | Example |
|---|---|---|
| Acute | Less than 90° | Clock hands at 2 o'clock |
| Right | Exactly 90° | Corner of a book |
| Obtuse | Between 90° and 180° | Clock hands at 4 o'clock |
| Straight | Exactly 180° | Clock hands at 6 o'clock |
Parts of a circle
| Part | Meaning |
|---|---|
| Centre | The fixed point in the middle |
| Radius | A line from the centre to the edge |
| Diameter | A line through the centre from edge to edge; diameter = 2 × radius |
Types of questions
- Name the figure or angle
- Sort angles
- Find the radius or diameter
- Count sides and corners
- Find the perimeter
Solved examples
Common mistakes
| Mistake | Correct |
|---|---|
| A ray can be measured | Only a line segment can be measured. |
| Diameter = radius ÷ 2 | Diameter = 2 × radius. |
| Judging an angle by the length of its arms | An angle is the amount of turn, not the arm length. |
| Adding only two sides for perimeter | Add all the sides of the shape. |
Daily life
Geometry is all around us: right angles in doors and books, circles in wheels and plates, angles made by clock hands, triangles in roofs and the perimeter of a park or a garden fence.
Tips for parents and teachers
- Go on a right angle hunt at home using the corner of a card.
- Use a clock to show acute, right, obtuse and straight angles.
- Draw circles with a bangle and fold them to find the diameter.
- Measure the sides of a book or table to find its perimeter.
- Let the child retry the challenges to earn 3 stars.
