What is a transversal
Any line that intersects two or more parallel lines.
Two angles whose measures add up to 180 degrees
What are supplementary angles?
If p and q are parallel, and r is a transversal, then angle D is congruent to angle E.
What is False?
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 (add 6 to both sides) 4x=128 x=32
Congruent angles formed by two intersecting lines. These angles are located across from each other.
What are vertical angles?
If the measure of angle 6 is 75 and the measure of angle 7 is 3x, what is the value of x?
What is angle H=105; and 3x=75 x=25
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.
What are Alternate Interior Angles?
Consecutive Interior
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.
Given that a || m, measure of angle 5=98°, then the measures of angles 3 and 4 are:
What is angle 3 is 82 degrees and angle 4 is 98 degrees
