Parallel Lines & Transversals

Front

What are Consecutive Interior Angles?

Back

Consecutive Interior Angles are pairs of angles that lie on the same side of a transversal and between two parallel lines.

Front

What are Corresponding Angles?

Back

Corresponding Angles are angles that are on the same side of the transversal and in corresponding positions relative to the two parallel lines. They are congruent.

Front

What is the relationship between Angles 4 and 6 if they are congruent?

Back

If Angles 4 and 6 are congruent, they are either corresponding angles or alternate interior angles.

Front

What are Vertical Angles?

Back

Vertical Angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is the definition of Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie on opposite sides of the transversal and between the two parallel lines. They are congruent.

Front

What is the relationship between ∠2 and ∠6 if they are corresponding angles?

Back

If ∠2 and ∠6 are corresponding angles, they are on the same side of the transversal and in corresponding positions, making them congruent.

Front

How can you identify Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie on opposite sides of the transversal and outside the two parallel lines. They are congruent.

Front

What is the significance of the Parallel Postulate in geometry?

Back

The Parallel Postulate states that through a point not on a line, there is exactly one line parallel to the given line.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What are Same-Side Interior Angles?

Back

Same-Side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two parallel lines. They are supplementary.
