Vocabulary
A line that intersects two or more lines.
What is a transversal?
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.
What are Same Side Interior Angles (Consecutive Interior)?
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle
What is 42 degrees?
If a pair of adjacent angles formed by intersecting line are side by side, they are either complementary or supplementary.
What is supplementary?
Angle 2 is 60 degrees. Angle 6 is 4x+20 degrees. This is the value of x.
What is x=10?
Two angles whose measures add up to 180 degrees
What are supplementary angles
Two angles whose measures add up to 90o
What are Complementary Angles?
What is the relationship between angles 4 and 5?
What are Alternate Interior Angles.
If lines are parallel, then corresponding angles are this.
What is congruent?
Angle 3 is 6x+10 degrees. Angle 5 is 80 degrees. This is the value of x.
What is x=15?
When 2 parallel lines are both intersected by a transversal, these angles occupy the same relative position in the intersection.
What are Corresponding Angles?
Lines that intersect at right angles
What are perpendicular lines?
If the measure of angle 8 is 112 degrees, what is the measure of angle 6?
What is 68 degrees?
If lines are parallel then conecutive interior angles are this.
What is supplementary?
If the measure of <1 is 4x-6 and the measure of <8 is 122, this is the value of x.
What is x=32?
Congruent angles directly opposite each other in an intersection
What are Vertical Angles?
The property of being equal in measure.
What is congruence (congruent)?
What is the realtionship between angles 1 and 4?
What are Vertical Angles?
If the measure of angle 2 is 30o , this is the measure of angle 7.
What is 30o ?
If the measure of <3 is 5x-100 and the measure of <6 is 3x, this is the value of x.
What is x=50?
When 2 parallel lines are both intersected by a transversal these angles are inside the two parallel lines and on opposite sides of the transversal.
What are Alternate Interior Angles?
Lines that do not intersect and have the same slope.
What are parallel lines?
If the measure of angle 1 is 37o , this is the measure of angle 8 and this is the angle relationship.
What is 37o? What is alternate exterior?
If angle 1 is98°, then this is the measure of angle 3 and this is the measure of angle 8.
What is 82 and 98 degrees?
If the measure of angle 4 is 8x+35 and the measure of angle 6 is 2x+5, then this is the value of x.
