Angles/Proportions/Percentage

Front

What is the ratio of red cars to blue cars if there are 6 red cars sold to every 3 blue cars?

Back

The ratio is 6:3, which simplifies to 2:1.

Front

What are vertical angles?

Back

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

Front

What are supplementary angles?

Back

Supplementary angles are two angles that add up to 180°.

Front

If angle 6 and angle 7 are vertical angles, what can we say about their measures?

Back

Angle 6 and angle 7 are equal in measure.

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What do you call angles that add up to 90°?

Back

Complementary angles.

Front

If two angles are supplementary, what is their total measure?

Back

Their total measure is 180°.

Front

How can you identify alternate interior angles?

Back

Alternate interior angles are on opposite sides of the transversal and inside the two lines.

Front

What is the definition of a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

If angle 1 is 70°, what is the measure of its supplementary angle?

Back

The supplementary angle is 110° (180° - 70°).
