5.2 Angles from Transversal Day 2 Do Now

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What is a transversal?

Back

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

Front

What does it mean for lines to be parallel?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel. They exist in different planes.

Front

What does it mean for lines to be perpendicular?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

Identify a pair of alternate exterior angles from the following: ∠4 and ∠8.

Back

∠4 and ∠8 are alternate exterior angles if they are on opposite sides of a transversal and outside the parallel lines.

Front

Identify a pair of alternate interior angles from the following: ∠3 and ∠7.

Back

∠3 and ∠7 are alternate interior angles if they are on opposite sides of a transversal and between the parallel lines.

Front

If line a is parallel to line b, what can be said about the angles formed by a transversal?

Back

The corresponding angles are equal, alternate interior angles are equal, and alternate exterior angles are equal.

Front

What is the relationship between the angles formed when two lines are cut by a transversal?

Back

The angles can be classified as corresponding, alternate interior, alternate exterior, and consecutive interior angles, each with specific relationships.
