Activity 1 - Parallel lines investigation
Activity 1 - Parallel lines investigation
Use the embedded GeoGebra applet to explore the relationship between parallel lines and related angles.
Note: Recall that a transversal is a line that intersects 2 other lines at 2 distinct points.
Note: The dashed brown line is a transversal that intersects 2 parallel lines.
Tick each of the boxes, one at a time, to explore corresponding, alternate and co-interior angles.
Drag the green points around to change the red and/or blue angle measures that appear.
Next, use the applet to help you answer the questions in the interactive.
Activity 2 - Finding the missing angles
Activity 2 - Finding the missing angles

Test your knowledge by completing the questions.
Activity 3 - Angle Chase
Activity 3 - Angle Chase
Click on the image to open the Angle Chase activity on Transum.org activity in a new tab.
Test your knowledge by filling in the values of the angles marked with a green dot.
If Chase 1 doesn't take that long to complete, try Chase 2 and 3.
Activity 4 - Angles Inside
Activity 4 - Angles Inside
Click on the image to open the Angles Inside page on the NRICH Maths website in a new tab.
Using your parallel line knowledge, as well as previous knowledge and understanding of angles, see if you can prove Alison’s statement.
Use the interactive to explore and then answer the questions in your exercise book or folder.
Draw diagrams of a parallelogram and a trapezium to answer those questions.
Show all your working.
