Chapter 3 Flashcards
Non Coplanar; they are not parallel and do not intersect
Skew lines
planes that do not intersect
Parallel planes
A line that intersects two or more coplanar lines at distinct points
Transversal
Non adjacent interior anglesm hat lie on opposite sides of the transversal
Alternate interior angles
Interior angles that lie on the same side of the transversal
Same-side interior angles
Lie on the same side of the transversal (T) and in corresponding positions
Corresponding angles
Non adjacent exterior angles that lie on opposite sides of the transversal
Alternate exterior angles
Arrows show the logical connections between the statements
Flow proof
A line that you add to a diagram to help explain relationships in proof
Auxiliary line
Am angle formed by a side and an extension of an adjacent side
Exterior angle of a polygon
Two non adjacent interior angles
Remote interior angles
The ratio of the vertical change (rise) to the horizontal change (run) between any two points
Slope (m)
The _____ _______ of an equation of a non vertical line is
y= mx+b, where (m) is the slope and (b) is the y-intercept
Slope-intercept form
The ______ _________ of an equation of a non vertical line is
