IM2 Topic 12 (Lesson 1)

Front

What is a corresponding angle?

Back

A corresponding angle is an angle that is in the same position on two parallel lines cut by a transversal.

Front

Identify the vertical angle to ∠1.

Back

The vertical angle to ∠1 is ∠6.

Front

If lines p and q are parallel and m∠7 = 126°, what is m∠2?

Back

m∠2 = 54°.

Front

What is an alternate interior angle?

Back

An alternate interior angle is an angle that is on opposite sides of the transversal and inside the two parallel lines.

Front

Identify the alternate interior angle to ∠3.

Back

The alternate interior angle to ∠3 is ∠5.

Front

What is the measure of angle DEF if it is given as 62°?

Back

m∠DEF = 62°.

Front

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

Back

Corresponding angles are equal.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal.

Front

How do you find the measure of an angle when two parallel lines are cut by a transversal?

Back

Use the properties of corresponding, alternate interior, or same-side interior angles.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.
