Angles on a Straight Line
There are two activities on this page on finding the missing angles on a straight line.
In this activity you are given the angle BAD, and you need to use your knowledge of angles to work out the angle CAD.
Once you have worked it out, click on the red angle to reveal the answer.
Click the button to create a new random question, or move the orange point to create your own angle problem

In this activity you are again practising the skills from above, but in a slightly more complex situation. This time there are three angles, and you have to work out the middle one from the information given.
As above, you can generate random questions, or create your own, but make sure the purple point stays on the right of the orange point (otherwise the wrong angles will be measured).

Ideas for Teachers
These two activities are excellent interactive ways to check students knowledge of angles on a straight line. Putting them up on the board, and creating random questions is agreat way to see if all students have grasped the concept, especially if you are using Show Me boards. Or yo could get the students to create their own problems and work out the answers (showing their working so they aren't just using the given answers.
