Parallel Line Proofs

Front

What is the Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

What is the Transitive Property in geometry?

Back

If angle A is equal to angle B, and angle B is equal to angle C, then angle A is equal to angle C.

Front

What does 'm ll n' represent in geometry?

Back

It indicates that line m is parallel to line n.

Front

What can be concluded if ∠1 ≅ ∠2 using the Corresponding Angles Postulate?

Back

It can be concluded that the lines being cut by the transversal are parallel.

Front

What is the definition of a transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What is the significance of the Given statement in a geometric proof?

Back

The Given statement provides the initial conditions or assumptions that are accepted as true for the proof.

Front

How can you identify vertical angles?

Back

Vertical angles are opposite angles formed by the intersection of two lines and are always equal.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
