| Question | Answer |
| Point | A point is a location with no size or shape |
| Line | A line is made up of points with no thickness or width |
| Line Segment | A measurable part of a line consisting of 2 endpoints |
| Ray | Part of a line that extends indefinitely in one direction |
| Plane | A plane is a flat surface made up of points and expands indefinitely in all directions |
| Collinear | Points that lie on the same line -- non-collinear; points that don't lie on the same lines |
| Coplanar | Points that lie on the same plane -- non-coplanar; points that don't lie on the same plane |
| Congruent Segments | If 2 segments have the same length then they are congruent |
| Segment Addition Postulate | If A, B, and C are collinear points and B is between A and C, then Ab + BC = AC |
| Distance Formula | The formula used to find the distance between the points on a coordinate plane d = square root of (x2 - x1)^2 + (y2 - y1)^2 |
| Midpoint formula | The formula used to mind the midpoint between 2 points M = (x1+x2/2, y1 +y2/2) |
| Segment Bisector | A segment, line, ray; plane that intersects a segment at the midpoint |
| Perpendicular | Two lines that intersect at a 90 degree angle (right angle) symbol is an upside down T |
| Perpendicular Bisector | A line, segment, or ray perpendicular to a segment at its midpoint |
| Parallel Lines | Two lines that never intersect symbol: || |
| Angle | Two rays with a common endpoint |
| Vertex | The common endpoint of an angle |
| Right angle | An angle with a measure of 90 degrees |
| Acute angle | An angle with a measure less than 90 degrees |
| Obtuse angle | An angle with a measure greater than 90 degrees |
| Straight angle | An angle with a measure of 180 degrees |
| Congruent angles | Two angles that have the same measure are congruent |
| Adjacent angles | Two angles that share a vertex and a side |
| Angle addition postulate | If angle ABD and angle DBC are adjacent, then measure of angle ABD + measure of angle DBC = measure of angle ABC |
| Angle bisector | A line or ray that divides an angle into 2 "=" points |
| Vertical angles | Two angles directly across from each other on intersecting lines *always congruent* |
| Complementary angles | 2 angles with measures that sum to 90 degrees "don't have to be adjacent* |
| Supplementary angles | 2 angles with measures that sum to 180 degrees "don't have to be adjacent* |
| Linear pair | Adjacent angles that form a straight line, they are supplementary |
| An angle is formed by 2 ___ with a common endpoint | rays |
| This common endpoint is called the ___ | vertex |
| Name an angle using ___ letters | 3 |
| A ray that divides an angle into ___ _____ ____ | 2 congruent angles |
| Two lines that _____ at a _____ ______ | intersect right angle |
| A line, segment, or ray _______ to a segment is its ______ | perpendicular midpoint |
