Quarter2 Independent Assignment #3 Properties of Parallel Lines

Front

What are corresponding angles?

Back

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

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

If two lines are parallel, what can be said about the corresponding angles formed by a transversal?

Back

The corresponding angles are equal.

Front

If ∠1 and ∠3 are corresponding angles, what can be concluded about the lines they lie on?

Back

The lines are parallel.

Front

What is the relationship between ∠2 and ∠7 if they are alternate exterior angles?

Back

They are equal in measure.

Front

If m∠3 = 56°, what is the measure of its corresponding angle?

Back

56°.

Front

What condition proves that line l is parallel to line m?

Back

If ∠3 ≅ ∠5, then line l is parallel to line m.

Front

What is the sum of the interior angles on the same side of a transversal?

Back

They are supplementary, meaning they add up to 180°.
