CHAPTER 3 Flashcards
(16 cards)
non-coplanar, 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 a distinct point
transversal
non adjacent interior angles that 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
nonadjacent 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 can add to a diagram to help explain relationships in proofs
auxiliary line
an angle formed by a side and an extension of an adjacent side
exterior angle of a polygon
two adjacent angles
remote interior angles
the ratio of the vertical change
slope
y = mx + b, where m is the slope and b is the y-intercept
slope- intercept form
y - y1 = m(x-x) where m is the slope and (x-x) is a point on the line
point- slope form
coplanar lines that do not intersect.
parallel lines
arrows that show the logical connections between the statements
flow proof
