11D Angles formed by Parallel Lines and a Transversal

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

If angle 6 is 25 degrees, what is angle 7?

Back

Angle 7 is 155 degrees, as it is the exterior angle to angle 6.

Front

What is the relationship between angle 4 and angle 2 if angle 4 = x + 15 and angle 2 = 3x - 5?

Back

Set the equations equal to each other to find x: x + 15 = 3x - 5.

Front

What is the sum of the angles formed by a transversal cutting two parallel lines?

Back

The sum of the angles formed by a transversal cutting two parallel lines is 180 degrees.

Front

What are the properties of angles formed by parallel lines and a transversal?

Back

The properties include: corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

How do you find the value of x in angle equations?

Back

To find x, set the equations for angles equal to each other and solve for x.

Front

What is the measure of angle D if it is given as 64 degrees?

Back

Angle D is 64 degrees.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary.

Front

If angle 1 = 70 degrees, what is the measure of angle 5?

Back

Angle 5 is also 70 degrees, as they are corresponding angles.
