1. Geometry Shapes Revision

2. Drawing Cubes How many cubes? Draw a front, side and top view.

4. Parallel Lines Parallel lines never meet

7. Polyhedra Prism Prisms are 3-D shapes that are the same shape all the way through.

8. Torus – 0 faces – 0 edges – 0 vertices Cylinder – 2 facesCube – 0 edges- 6 faces – 0 vertices- 12 edges - 8 vertices

9. cone Sphere pyramid

10. Nets

12. Platonic Solids

13. Euler’s Formula F + V – E =2 Eg: A shape has 10 faces and 8 vertices. How many edges does it have? 10 + 8 - ___ = 2 18 - ___ = 2 18 – 16 = 2, therefore it has 16 edges.

14. You Try It A shape has 4 vertices and 6 edges. How many faces does it have? What shape is it? A shape has 8 faces and 12 edges. How many vertices does it have? What shape is it?

15. Interior angles of a Triangle The angles in a triangle add up to 180° If x = 56° and y = 48°, determine z 180° – 56° – 48° = z = 76°
