NOW DO THE ACTIVITIES BELOW ...
1) UNDERSTANDING VERTICALLY OPPOSITE ANGLES: Below, is an activity where you can see lots of different vertically opposite angles. On the webpage, you move lines around, to see how the angles at the point where two lines cross change.
Once you have clicked on this LINK, scroll down to the comment "Have a play with them yourself...", and drag the points A, B, C and D and notice what happens to the angles:
- do the pairs of vertically opposite angles always stay equal?
- do the angles on a straight line always add to 180 degrees?

3) FINDING ANGLES : In this next activity, you have to find the missing angle at a point or on a straight line, by subtracting all the other angles from 360 degrees or 180 degrees. Enter your answers in the boxes to see if you are right. Follow this LINK . Everyone try questions 1, 2 and 5. If you feel like a challenge, have a go at the other questions too!
