Review 3.1 - -3.2

Front

What is the definition of Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the definition of Vertical Angles?

Back

Vertical Angles are the angles opposite each other when two lines cross. They are always equal.

Front

What is the definition of Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in the same position on two different lines in relation to a transversal.

Front

What is the definition of Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that are on opposite sides of the transversal and outside the two lines.

Front

If Angle 4 is equal to 105 degrees, what is Angle 5 equal to and why?

Back

Angle 5 is equal to 105 degrees because they are Alternate Interior Angles.

Front

What is the relationship between Angle x and Angle y if they are Alternate Exterior Angles?

Back

Angle x and Angle y are equal because Alternate Exterior Angles are congruent.

Front

How do you find the measure of a missing interior angle in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees. Subtract the known angles from 180 to find the missing angle.

Front

What is the measure of the missing interior angle if the other two angles are 60 degrees and 40 degrees?

Back

The missing angle is 80 degrees (180 - 60 - 40 = 80).

Front

What is the value of x if Angle 1 is 31 degrees and it is a Vertical Angle to Angle x?

Back

x = 31 degrees because Vertical Angles are equal.

Front

What is the sum of the angles in a quadrilateral?

Back

The sum of the angles in a quadrilateral is always 360 degrees.
