What is a transversal
Any line that intersects two or more parallel lines.
Draw Parallel lines
Straight lines that never intersect
If a pair of adjacent angles formed by intersecting line are linear pairs, what is their relationship?
What is supplementary
Draw Complementary Angles
Two angles whose measures add up to 90
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent
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.
Draw Linear Pair Angles
A pair of adjacent angles formed by intersecting lines. These angles are also supplementary.
To prove that lines are parallel one must understand that same side interior angles are.
What is supplementary
Draw 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.
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
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.
Draw supplementary angles.
Two angles that add up to 180
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 Angle?
Given that the measure of angle 5 is 98°, then the measures of angles 3 and 4 are:
Angle 3 =82 degrees and angle 4= 98 degrees
If an angle 1 is equal to 93, what is angle 2 equal to?
What is 87 Deegrees
