Angles in parallel lines
Identify and use alternate, corresponding and co-interior angles in parallel lines
What you'll learn
- 1
Imagine two train tracks running side by side — they never meet. Those are parallel lines!
- 2
What do we call lines that never meet?
- 3
Drag the angle markers to show which angles are equal — look for the 'F' shape!
- 4
Find angle a when the transversal makes a 70° angle on one parallel line.
- 5
Use the number line to find the missing angle — remember alternate angles make a Z shape!
- 6
If an alternate angle is 50°, what is the other alternate angle?
- 7
Which shape do corresponding angles make?
