- 1PointA point in geometry is a location. It has no size.
- 2LineA line is defined as a line of points that extends infinitely in two directions.
- 3PlaneA plane is a flat, two-dimensional surface that extends infinitely far.
- 4CollinearThree or more points are said to be collinear if they lie on a single straight line.
- 5CoplanarA set of points that lie on the same plane are said to be coplanar.
- 6SegmentA line segment is a part of a line that is bounded by two distinct endpoints and contains every point on the line between its endpoints.
- 7RayA ray is a line with a single endpoint that extends infinitely in one direction.
- 8Opposite RaysA pair of opposite rays are two rays that have the same endpoint and extend in opposite directions.
- 9MidpointThe midpoint is the middle point of a line segment.
- 10Segment BisectorA segment bisector is a point, a line, a ray, or a line segment that bisects another line segment.
- 11Congruent SegmentsCongruent segments are segments that are equal in length.
- 12Right AngleA right angle is an angle of exactly 90°.
- 13Obtuse AnglesAn obtuse angle is more than 90° but less than 180°.
- 14Straight AngleA straight line through the vertex of the angle. The measure of a flat angle is thus always 180°.
- 15Congruent AnglesCongruent Angles have the same angle in degrees.
- 16Acute AnglesAn angle smaller than a right angle. The range of an acute angle is between 0 and 90 degrees.
- 17Adjacent AnglesTwo angles are adjacent when they have a common side and a common vertex and don't overlap.
- 18Linear PairThe measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
- 19Complementary AnglesTwo angles are complementary when they add up to 90 degrees.
- 20Supplementary AnglesTwo angles are supplementary when they add up to 180 degrees.
- 21Vertical AnglesThe angles opposite each other when two lines cross. They are always equal.
- 22PerimeterPerimeter means a path that surrounds an area.
- 23AreaThe area of a figure is the number of unit squares that cover the surface of a closed figure.
- 24RadiusA radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length.
- 25CircumferenceThe circumference of a circle is the distance around it.
- 26LegA leg of a triangle is one of its sides.
- 27HypotenuseThe hypotenuse is the side of a right triangle that's opposite the 90-degree angle.
- 28Reflection
