Parallel Lines and Transversals 1
what is a line that intersects two or more lines at different points called?
What is a transversal?
what lie inside the two lines?
interior angles
If two parallel lines are cut by a transversal, what is the relationship between the same side interior angles formed?
Same side interior angles add up to 180.
If two lines are parallel and cut by a transversal, then consecutive interior angles are supplementary, and if one of those interior angles is 7x+12 and the other is 3x+8...
What are the measures of each angle?
56 degrees and 124 degrees
two lines that are the same distance apart and will never touch
What is parallel lines
If degrees of angles are = to each other, angles are this
What is congruent
If two parallel lines are cut by a transversal, and alternate interior angles are congruent, and if one of those alternate interior angles is x+15, and the other is 2x+5.
What is the value of x?
x = 10
Two parallel lines are cut by a transversal, angles 1 and 2 are corresponding, if angle 1 measures 95 degrees, what is the measure of angle 2?
95 degrees.
2 angles sum 180 degrees
What is supplementary angles
what are on opposite sides of the transversal and inside the parallel lines?
What is alternate interior angles?
What are corresponding angles?
What is the angles that are in the same position, same side of the transversal but in different groups. (one interior, one exterior)
If two parallel lines are cut by a transversal, what is the relationship between the vertical angles formed?
Vertical angles share the same vertex and are congruent.
Two parallel lines are cut by a transversal and angles 1 and 2 are corresponding. If angle 1 measures 40 degrees, what is the angle measure of the angle complementary to angle 1?
50 degrees.
Angle 1 and Angle 2 are Alternate interior angles, Angle 1 is 88 degrees, this is the measure of angle 2
What is 88 degrees
2 angles that sum 90 degrees
What is complementary angles
Alternate exterior angles are ___ (location)
outside the parallel lines on opposite sides of the transversal
If two parallel lines are cut by a transversal, what is the relationship between the same side exterior angles formed?
Same side exterior angles add up to 180.
Two parallel lines are cut by a transversal and angles 1 and 2 are corresponding. If angle 1 measures 40 degrees, what is the angle measure of the angle supplementary to angle 1?
140 degrees
Angle 1 and angle 2 are corresponding angles. Angle 2 is 46 degrees, this is the measure of angle 1
What is 46 degrees
What are the three types of angle relationships that are supplementary.
Linear pair, consecutive interior, consecutive exterior
what lie outside the two lines?
What is exterior angles?
Two parallel lines are cut by a transversal. If Angles 3 and 4 are alternate exterior angles and the measure of angle 3 is 80 degrees, what is the measure of angle 4?
80 degrees
Two lines are cut by a transversal. If angles A and B are same side exterior angles and are supplementary, does that prove that the lines are parallel? Why?
Yes. Same side exterior angles are supplementary.
Angle 3 and angle 4 are supplementary angles, angle 3 measures 37 degrees, this is the measure of angle 4
What is 143 degrees
