2. Angles, acute angles, obtuse angles, right angles, straight angles.

3. Reinforce and develop concepts of lines and angles.

Solve the problem and click the correct answer. If correct, a check mark will appear. For help, put the pointer over the ? below the work area. Click the problem, press the ENTER or RETURN key, or click on the reset problem button to set a new geometry line or angle problem.

Click the yellow check mark to keep score! Select the number of problems by clicking up and down by the 25 default. After you think you've correctly answered a problem, reset it. Each time you reset the problem, the left counter increases for a correct answer; the right counter counts the number of problems you've done. The black check mark will not appear when keeping score. When you've finished, your score will be shown.

The spinning math signs mean we're waiting on the server - if it goes too long, you can try pressing the reset button again.
