Question

SOLVE EACH PROBLEM.

derive relationship among angles formed by parallel lines cut by a transversal.

Alternate Interior Angles:

Alternate Exterior Angles:

Corresponding Angles:​

Answer 1

Answer:

Let the two alternate interior angles be x and y .

Then , relation between x and y is :

x - y = 0

Or x = y

Let the two corresponding angles be x and y :

Then , relation between x and y is ;

x + y = 180°
