Geometry Ch.3 part 1

Vocabulary for Chapter 3 - Parallel & Perpendicular Lines (part 1)

TermDefinition
Alternate Interior Angles For two lines intersected by a transversal, a pair of nonadjacent angles that lie on opposite sides of the transversal and between the parallel lines. These angles are congruent.
Alternate Exterior Angles For two lines intersected by a transversal, a pair of nonadjacent angles that lie on opposite sides of the transversal and outside the parallel lines. These angles are congruent.
Corresponding Angles For two lines intersected by a transversal, a pair of angles that lie on the same side of the transversal and on the same sides of the other two lines. These angles are congruent.
Same-Side (Consecutive) Interior Angles For two lines intersected by a transversal, a pair of angles that lie on the same side of the transversal and between the other two lines. These angles are supplementary.
Same-Side (Consecutive) Exterior Angles For two lines intersected by a transversal, a pair of angles that lie on the same side of the transversal and outside the other two lines. These angles are supplementary.
Transversal A line that intersects two coplanar lines at two different points.
Parallel Lines Lines in the same plane that do not intersect.
Perpendicular Lines Lines that intersect at 90 degree angles.
Skew Lines Lines that are not coplanar, not parallel and do not intersect.
Parallel Planes Planes that do not intersect.
Complementary Angles Two angles whose measures have a sum of 90 degrees.
Supplementary Angles Two angles whose measures have a sum of 180 degrees.
Vertical Angles The nonadjacent angles formed by two intersecting lines. These angles are congruent.
Slope-Intercept Form One form of a linear equation written as y = mx + b, where m is the slope and b is the y-intercept.
Point-Slope Form One form of a linear equation written as y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
Standard Form One form of a linear equation written as Ax + By = C, where A is a positive, whole number and x and y are located on the same side of the equation.
Slope Formula the change in y = (y2 - y1) the change in x (x2 - x1)
Rise The difference in the y-values of two points on a line (aka vertical distance).
Run The difference in the x-values of two points on a line (aka horizontal distance).
Slope A measure of the steepness of a line. If (x1, y1) and (x2, y2) are any two points on the line, the slope of the line, known as m, is represented by the equation m = (y2 - y1)/(x2 - x1).
