  1. All about Shapes Ask Boffin!

  2. Properties of Shapes • Number of sides • Number of angles • Number of lines of symmetry • Regular or irregular • Right Angles • Parallel lines

  3. Shapes Triangles Quadrilaterals Polygons Regular Shapes Key Words

  4. Quadrilaterals Shapes with 4 sides!

  5. What shape is this?

  6. A Square

  7. Properties of a Square • Has 4 equal sides • Has 4 equal angles • Each angle is a right angle • Has 4 lines of symmetry • Is a regular shape

  8. What shape is this?

  9. A Rectangle

  10. Properties of a Rectangle • Has 2 pairs of equal sides • Has 4 equal angles • Each angle is a right angle • Has 2 lines of symmetry • Is an irregular shape

  11. What shape is this?

  12. A Parallelogram

  13. Properties of a Parallelogram • Has 2 pairs of equal sides • Has 2 pairs of equal angles • Opposite sides are parallel • Has NO lines of symmetry • Is an irregular shape

  14. What shape is this?

  15. A Rhombus

  16. Properties of a Rhombus • Has 4 equal sides • Has 2 pairs of equal angles • Opposite sides are parallel • Has 2 lines of symmetry • Is an irregular shape

  17. What shape is this?

  18. A Trapezium

  19. Properties of a Trapezium • Has unequal sides • One pair of opposite sides are parallel • Usually has NO lines of symmetry • Is an irregular shape

  20. Quadrilaterals Shapes with 4 sides!

  21. Triangles Shapes with 3 sides!

  22. What type of triangle is this?

  23. An Equilateral Triangle

  24. Properties of an Equilateral Triangle • Has 3 equal sides • Has 3 equal angles • Each angle is a 60o angle • Has 3 lines of symmetry • Is a regular shape

  25. What type of triangle is this?

  26. A Right Angled Triangle

  27. A Right Angled Triangle is different It may be scalene or it may be isosceles But it always has a right angle!

  28. Properties of a Right Angled Triangle It will be isosceles and have 1 line of symmetry when these 2 sides are equal. • Has 1 right angle • May be an isosceles triangle • May have 1 line of symmetry • Is an irregular shape

  29. Triangles Shapes with 3 sides!

  30. Key Words • Regular Shape • Parallel • Perpendicular • Vertex • Diagonal • Bisect

  31. Regular Shape Shapes are regular when • All their sides are the same length • All their angles are the same size

  32. Polygons Shapes with many sides!

  35. Properties of a Regular Hexagon • Has 6 equal sides • Has 6 equal angles • Has 6 lines of symmetry

  36. What shape is this?

  37. A Pentagon

  38. Properties of a Regular Pentagon • Has 5 equal sides • Has 5 equal angles • Has 5 lines of symmetry

  39. Polygons Shapes with many sides!

  40. Regular shapes • All the sides are the same length • All the angles are equal • Have the same number of lines of symmetry as the number of sides
