The way to show that lines b and c are parallel in the diagram given is to apply the: B. Corresponding Angles Converse Postulate
Note the following:
- From the diagram given, parallel lines b and c are cut across by transversal g.
- One of the angles formed at the point of intersection of line b and transversal g is 51 degrees.
- Another angle formed at the intersection of line c and transversal g is also 51 degrees.
Thus:
Both angles lie in corresponding positions to each other. Both angles are corresponding angles.
Since both angles are corresponding angles that are congruent, lines b and c are therefore parallel lines based on the Converse of the Postulate of Corresponding Angles.
Therefore, a way to show that lines b and c are parallel in the diagram given is to apply the: B. Corresponding Angles Converse Postulate
