- 1. Objective:To describe properties of solid shapes such as perpendicular andparallel lines, faces and edges
- 2. PART 1SOLID SHAPES
- 3. Two-dimensional Shapes (2D) • These shapes are flat and can only be drawn on paper. • They have two dimensions – length and width. • They are sometimes called plane shapes.
- 4. Three-dimensional Shapes (3D) • These shapes are solid or hollow. • They have three dimensions – length, width and height.
- 5. Face • Part of a shape that is flat.(Or curved) • E.g. A cube has 6 of these.
- 6. Edge • The line where two faces meet. • E.g. A cube has 12 of these.
- 7. Vertex (Vertices) • The place where three or more edges meet. • This pyramid has 4 of these.
- 8. Parallel • These type of lines stay the same distance apart for their whole length. They do not need to be straight or the same length.
- 9. Perpendicular • A line that is drawn in a right angle to another line . • In solid shapes edges could be at a right angle to one another. • Faces could also be at right angles to one another.
- 10. Cube • A three-dimensional shape which has 6 square faces all the same size. Some faces parallel Some edges parallel Some faces perpendicular Some edges perpendicular
- 11. Cuboid • A three-dimensional shape which has 6 rectangular faces. Some faces parallel Some edges parallel Some faces perpendicular Some edges perpendicular
- 12. Sphere • A perfectly round three-dimensional shape, like a ball. It has only one curved face. No parallel faces or edges No perpendicular faces or edges
- 13. Hemisphere • A three-dimensional shape that is half a sphere. No parallel faces or edges No perpendicular faces or edges
- 14. Cone • A three dimensional shape with a circle at its base and a pointed vertex. No parallel faces or edges No perpendicular faces or edges
- 15. Cylinder • A three-dimensional shape with circular ends of equal size. Some faces parallel Some edges parallel Some faces perpendicular No edges perpendicular
- 16. Pyramid • A three-dimensional shape which has a polygon for its base and triangular faces which meet at one vertex. •E.g. Triangular pyramid • Square pyramid • Hexagonal pyramid • Pentagonal pyramid
- 17. Square base pyramid No faces parallel Some edges parallel No faces perpendicular Some edges perpendicular
- 18. Prism • A three dimensional shape that has the same cross-section all along its length.
- 19. Written task SOME PARALLEL FACES NO PARALLEL FACES SOME PERPENDICULAR FACES Cube CuboidNO PERPENDICULAR FACES Cone Square based- Pyramid Sphere Hemispere
- 20. Written task SOME PARALLEL EDGES NO PARALLEL EDGESSOME PERPENDICULAR EDGES Cube Cuboid Square-based pyramidNO PERPENDICULAR EDGES Sphere Hemisphere Cone
- 21. PART 2PLANE SHAPES
- 22. Polygons Two-dimensional shapes that have sides made from straight lines. • E.g. triangles squares hexagons
- 23. Quadrilaterals • Any two-dimensional shapes with four straight sides. • E.g. square rhombus rectangle trapezium kite
- 24. Rectangle • A four sided two- dimensional shape with two pairs of parallel sides that meet at right angles.
- 25. Kite • A two-dimensional shape with two shorter sides of equal length and two longer sides of equal length.
- 26. Rhombus • A two-dimensional four sided shape with opposite sides that are parallel and all the sides are the same length.
- 27. Trapezium • A two-dimensional shape with four sides.One pair of sides is parallel with one side longer than the other.
- 28. Pentagon • A two-dimensional shape with five straight sides and five angles.
- 29. Hexagon • A two-dimensional shape with 6 straight sides and 6 angles.
- 30. Octagon • A two-dimensional shape with 8 straight sides and 8 angles.
- 31. What do we call a shape with: 7 Sides? 9 Sides? 10 Sides?
- 32. Circle • A round flat two- dimensional shape.
- 33. Square • Two dimensional shape with 4 sides of the same length and 4 90 angles.
- 34. Triangle • Two-dimensional shape with three straight sides and three angles. • Can you name 4 different kinds?
