Unit 3 Transversals and Algebra Flashcard

Front

What are transversals in geometry?

Back

Transversals are lines that intersect two or more other lines at distinct points. They are often used to study the relationships between angles formed when they cross parallel lines.

Front

What is the Corresponding Angles Postulate?

Back

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

Front

What is the Alternate Interior Angles Theorem?

Back

If a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

What is the value of x if line l is parallel to line m? (x = ?)

Front

Find the measure of angle C if the lines are parallel. (∠C = ?)

Back

∠C = 116°

Front

What is the value of x if the lines cut by the transversal are parallel? (x = ?)

Back

Front

Solve for x in the equation: 180 - x = 172. (x = ?)

Front

Find the measure of angle 1 if the lines cut by the transversal are parallel. (∠1 = ?)

Back

∠1 = 44°

Front

What is the definition of alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal.

Front

What is the definition of same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between the two lines and on the same side of the transversal.
