Angle Theorems-1.pptx tutorial for grade 6

Tutorials for kids.

1. Angle Theorems Angle at a point, vertically opposite angles, alternate angle, corresponding angle and angles in triangle

2. Review of angle on a straight line

3. Angle at a point The sum of angle at a point is 360 for example in the diagram below a+b+c+d = 360

4. Example: find the value of the missing side in the question

5. Find the value of m in the figure below

6. Now try this

7. Now try this?

8. Can you figure out the value of x in this question?

9. Vertically opposite angles Vertically opposite angles are the angles when two lines cross each other. Vertically opposite angles are equal; I.e a = b

10. Take a look at this

11. Questions find the values of the missing sides?

12. Now try this?

13. Miscellaneous question

14. Alternate angle The alternate angles are the pair of angles, which are formed when the parallel lines are cut by a transversal.

15. Corresponding angle Corresponding angles are angles formed on the same sides of a parallel line joined together by a transversal line.

16. Example: find the value of the missing sides
