Q1W7 GEO Skew&Paralell/ Angles / Transversal

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

Define a linear pair of angles.

Back

A linear pair of angles consists of two adjacent angles formed when two lines intersect. The sum of the angles in a linear pair is always 180 degrees.

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 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. They are equal when the lines are parallel.

Front

What are alternate interior angles?

Back

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

Front

What are perpendicular lines?

Back

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

Front

What is a transversal?

Back

A transversal is a line that crosses at least two other lines. It creates several angles, including corresponding, alternate interior, and same-side interior angles.

Front

How do you identify a linear pair in a diagram?

Back

A linear pair can be identified by looking for two adjacent angles that share a common side and whose non-common sides form a straight line.

Front

What is the relationship between parallel lines and corresponding angles?

Back

When two parallel lines are cut by a transversal, the corresponding angles are equal.

Front

What is the sum of the angles in a linear pair?

Back

The sum of the angles in a linear pair is always 180 degrees.
