---|---|---|---|---|---|
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).
