In this picture, two parallel lines are cut by a third line, called a transversal. How many vertical angle pairs can you find?

In this picture, two parallel lines are cut by a third line, called a transversal. What is the maximum number of Linear Pairs of angles you can find?
2 Linear Pairs
4 Linear Pairs
6 Linear Pairs
8 Linear Pairs
We assume that, since the lines are parallel, Corresponding Angles are congruent - for example ∠5≅∠1 . Check any box with Corresponding Angles.
∠1 and ∠2
∠2 and ∠6
∠4 and ∠8
∠3 and ∠7
Suppose we assume that ∠5≅∠1 . What is true about ∠1 and ∠4 ?
∠1 and ∠4 form a linear pair, so are supplementary
∠1 and ∠4 are adjacent angles which share a side
∠1≅ ∠4 because they are vertical angles
∠1 and ∠4 are right angles
So, if m∠2+m∠4=180° and m∠6=m∠2 , we can substitute to get this equation: m∠6+m∠4=180° . Conclude
∠6 and ∠4 are complementary (sum to 90° )
∠6 and ∠4 are supplementary (sum to 180° )
∠6 and ∠4 are adjacent
∠6 and ∠4 form a linear pair
