The number of pairs of angles formed are about 7 types.
What are the Pairs of Angles Formed by a Transversal and Two Lines?
In the image given, when transversal t crosses the two lines, a and b, 8 angles are formed.
The pairs of angles formed are:
- Vertical angles, for example, angles 2 and 4.
- Linear pair angle, for example angles 1 and 2.
- Corresponding angles, for example angles 1 and 5.
- Alternate interior angles, for example angles 4 and 5.
- Alternate exterior angles, for example angles 1 and 8.
- Same-side interior angles, for example angles 3 and 5.
- Same-side exterior angles, for example angles 2 and 8.
Therefore, there are about 7 types of pairs of each type of angles formed.
