Angle Relationships Part 3

100

What is a transversal

Any line that intersects two or more parallel lines.

100

Parallel lines

Straight lines that never intersect

100

Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle

What is 42

100

If a pair of adjacent angles formed by intersecting line are linear pairs, what is their relationship?

What is supplementary

100

If a transversal cuts two parallel lines, how many angles are formed?

What are 8

200

What are supplementary angles?

Two angles whose measures add up to 180 degrees

200

Complementary Angles

Two angles whose measures add up to 90

200

What is the relationship between angles 3 and 6 ?

What are Alternate Interior Angles.

200

One way to prove that lines are parallel lines is through understanding that corresponding angles are

What is congruent

200

What is the converse of the alternate interior angles theorem?
If p and q are parallel, and r is a transversal, then angle D is congruent to angle E.

If r is a transversal and angle D is congruent to angle E, then p and q are parallel.

300

When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.

What are Corresponding Angles.

300

Linear Pair Angles

A pair of adjacent angles formed by intersecting lines. These angles are also supplementary.

300

If the measure of angle 4 is 112, what is the measure of angle 6?

What is 68. (same-side interior angles)

300

To prove that lines are parallel one must understand that same side interior angles are.

What is supplementary

300

If the measure of angle 1 = 4x-6 and the measure of
angle 5 =122, what is the value of x?

What is 4x-6=122
+6 +6
4x=128
x=32

400

What are vertical angles?

Congruent angles formed by two intersecting lines. These angles are located across from each other.

400

Alternate Exterior Angles

If two parallel lines are intersected by a transversal, these angles are located on the outside of the two parallel lines on opposite sides of the transversal.

400

What is the relationship between angles 5 and 8?

What are Vertical Angles.

400

If the measure of angle 2 is 30 degrees , what is the measure of angle 6?

What is 30.

400

If the measure of angle 6 = 75 and the measure of angle 7=3x, what is the value of x?

What is angle H=105; and 3x=75
x=25

500

What are Alternate Interior Angles?

When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.

500

Same-side angles (consecutive)

If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.

500

If the measure of angle 2 is 37 degrees, what is the measure of angle 7? What is the angle relationship?

What is 37 and Alternate Exterior.

500

Given that a || m, measure of angle 5=98°, then the measures of angles 3 and 4 are:

What is angle 3 =82 degrees and angle 4= 98 degrees

500

If the measure of angle 4= 5x+3 and the measure of angle 6= 8x-5, then find the value of x and find the measure of angles 4& 6?

What is 5x+3+8x-5=180
13x-2=180
13x=182
x=14
Angle 4=5(14)+3=73 degrees
Angle 6= 8(14)-5=107 degrees
