Unit 3 Review

Front

What are alternate interior angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different parallel lines cut by a transversal. They are equal.

Front

What does it mean for lines to be skew?

Back

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

Front

How do you solve for x in angle problems?

Back

To solve for x in angle problems, use the properties of angles (like alternate interior or corresponding angles) and set up equations based on their relationships.

Front

What is the value of y if the equation is y + 10 = 39?

Back

y = 29.

Front

What is the relationship between skew lines and planes?

Back

Skew lines are not in the same plane; they exist in different planes and do not intersect.

Front

How do you identify corresponding angles in a diagram?

Back

Look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the significance of transversal lines in geometry?

Back

Transversal lines intersect two or more lines, creating various angle relationships such as alternate interior, corresponding, and same-side interior angles.

Front

If angle 4 is 50 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 50 degrees.

Front

What is the definition of a transversal?

Back

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