Geometry: the Shape Town Story
A short read for Class 5 before you play. These notes are written for this page.
📍 Points and lines
Every shape starts with a point. Join two points and you get a line segment. Let it run on for ever one way and it becomes a ray.
📐 Angles
An angle is the turn between two rays. A quarter turn is a right angle, a half turn is a straight angle and a full turn makes 360 degrees.
🔺 Triangles
Triangles have three sides and three angles that always add up to 180 degrees. They are named by their sides and by their angles.
🟦 Four-sided shapes
Squares, rectangles, parallelograms and trapeziums all have four sides. Their four angles always add up to 360 degrees.
⭕ Circles
A circle is round with no corners. The distance from the centre to the edge is the radius, and the diameter is twice as long.
🧊 Solids
Solids have faces, edges and corners. A cube has 6 faces, 12 edges and 8 corners, while a cylinder and a cone have curved surfaces.

Worked examples
65 + 45 = 110, and 180 - 110 = 70, so the third angle is 70°.
The radius is half of the diameter, so it is 18 cm.
A cuboid has 3 pairs of equal faces, so it has 6 faces.
This Geometry worksheet for Class 5 maths gives you online activities and interactive games that turn shapes into play. Every activity has a goal, a hint and a short fact, so children learn while they enjoy.
Complete Guide: Maths Geometry Class 5
This guide is for Class 5 students, parents and teachers. It explains shapes, angles and solids in simple words and shows how to use the quiz, labs and games on this page.
Introduction to Geometry
Geometry helps children describe the world around them. They learn the names and properties of shapes and use simple rules to find missing angles and lengths.

| Topic | Key idea |
|---|---|
| Right angle | 90 degrees, which is 1/4 of a full turn. |
| Straight angle | 180 degrees, which is 1/2 of a full turn. |
| Triangle | Three angles that add up to 180 degrees. |
| Quadrilateral | Four angles that add up to 360 degrees. |
| Circle | The diameter is twice the radius. |
Types of questions you may see
- Name the angle or the line.
- Classify a triangle or a quadrilateral.
- Find a missing angle.
- Radius and diameter.
- Count the faces, edges and vertices.
Solved examples
It is obtuse, because it is more than 90 degrees.
It is isosceles, because two sides are equal.
120 + 80 + 70 = 270, and 360 - 270 = 90 degrees.
9 × 2 = 18 cm.
It has 9 edges.
A cone.
Common mistakes
| Mistake | Correct idea |
|---|---|
| Calling every four-sided shape a square. | A square needs four equal sides and four right angles. |
| Mixing up radius and diameter. | The diameter goes through the centre and is twice as long. |
| Thinking a longer arm makes a bigger angle. | The size of an angle is the amount of turn, not the length of the arms. |
| Counting only the visible faces of a cube. | Remember the faces at the back and bottom. |
Geometry in daily life
Children see angles in clock hands and doors, triangles in roofs and bridges, circles in wheels and cuboids in boxes. Naming them at home builds confidence.
Tips for parents and teachers
- Make angles with two pencils and compare them with a book corner.
- Build triangles and quadrilaterals with straws.
- Go on a shape hunt around the house.
- Use boxes and tins to talk about faces, edges and vertices.

Geometry Class 5 FAQs
What is geometry in Class 5 maths?
Geometry is the part of maths that studies shapes, lines, angles and solids. In Class 5 children learn about points, lines, angles, triangles, quadrilaterals, polygons, circles and solid shapes.
What is the difference between a point, a line, a line segment and a ray?
A point is an exact position with no size. A line segment is a straight piece with two end points. A ray starts at one point and goes on for ever in one direction, and a line goes on for ever in both directions.
What are the types of angles?
An acute angle is smaller than 90 degrees, a right angle is exactly 90 degrees and an obtuse angle is between 90 and 180 degrees. A straight angle is 180 degrees. A right angle is 1/4 of a full turn and a straight angle is 1/2 of a full turn.
What are the types of triangles?
By sides, an equilateral triangle has three equal sides, an isosceles triangle has two equal sides and a scalene triangle has no equal sides. By angles, an acute triangle has three acute angles, a right triangle has one right angle and an obtuse triangle has one obtuse angle.
What are the types of quadrilaterals?
A quadrilateral has four sides. Common types are the square, rectangle, parallelogram, rhombus and trapezium. A square has four equal sides and four right angles, and a trapezium has just one pair of parallel sides.
What is a polygon and how are polygons named?
A polygon is a closed shape made of straight sides. We name it by the number of sides: triangle 3, quadrilateral 4, pentagon 5, hexagon 6, heptagon 7 and octagon 8.
What are the parts of a circle?
The centre is the middle point, the radius is a line from the centre to the edge and the diameter is a line through the centre from edge to edge. The edge itself is called the circumference.
What is the relation between radius and diameter?
The diameter is twice the radius, and the radius is half the diameter. For example a circle with radius 5 cm has diameter 10 cm.
What is the angle sum of a triangle and a quadrilateral?
The three angles of any triangle add up to 180 degrees, and the four angles of any quadrilateral add up to 360 degrees. We use these facts to find a missing angle.
What are faces, edges and vertices of solid shapes?
A face is a flat surface, an edge is where two faces meet and a vertex is a corner. A cube has 6 faces, 12 edges and 8 vertices.
What are parallel and perpendicular lines?
Parallel lines always stay the same distance apart and never meet, like the two rails of a railway track. Perpendicular lines meet at a right angle, like the corner of a page.
What can children do on this page?
Children can take a 20-question online quiz with a full review, play five games, try five online activities, finish five challenges, run the Geometry Lab and two virtual experiments, and fill in a 16-question practice sheet with a Show answers button.
