Lines and Angles
A ________________________ is a line that cuts two or more coplanar lines at different points.
What is transversal?
The symbol for perpendicular lines.
What is upside down capital T?
The symbol for parallel.
What is the double l, (ll)?
Two equations in point slope form with the same slope will be:
What is parallel?
What is y=mx+b?
The number of corresponding angle pairs that are formed when a transversal cuts through two lines.
What is 4?
If two lines are perpendicular, then there will be ______ 90 degree angles
What is 4?
These can be added on lines to indicate that the lines are parallel.
What are arrows?
If a line is parallel to a given line, and another line is parallel to the same given line, then all three lines are going to be:
What is parallel?
Two lines that are parallel will have this in common.
What is the same slope?
The type of lines that are not coplanar, and never intersect.
What is skew?
Two lines that intersect to form a linear pair of congruent angles are going to be:
What is perpendicular?
When two parallel lines are cut by a transversal, then the alternate exterior angles will be:
What is congruent?
True or False: If one pair of vertical angles are 90 degrees, then the other pair of vertical angle at that intersection will be 90 degrees.
What is true?
The slopes of perpendicular lines will be:
What is opposite (or negative) reciprocals?
What is alternate exterior angles?
When a 90 degree angle is intersected by another line, then the two angles that are formed will be:
What is complementary?
What is that the lines are parallel?
When two lines are parallel, and the transversal is perpendicular to those lines, then each angle will be
What is 90 degrees?
what must you give to one of the slopes of a perpendicular line.
What is -1?
The synonym for same-side interior angles.
What is consecutive interior angles?
The sum of all the angles that are formed when two lines are perpendicular to each other.
What is 360 degrees?
If one of the alternate interior angles is 50 degrees, then the other one would have to be _______ degrees for the two lines to be parallel.
What is 50?
When two parallel lines have a perpendicular transversal, then the same-side interior angles will always be
What is supplementary?
In the following equation, identify the slope of a line parallel to the given line, and the slope of the line that is perpendicular to the given line:
y =4x +3
What is slope of 4 for parallel, and -1/4 for perpendicular?
