- geometric construction
- a geometric drawing that used a limited set of tools, usually a compass and straight edge
- conjecture
- an unproven statement based on obervations
- collinear points
- points that lie on the same line
- coplanar points
- lie on the same plane
- inductive reasoning
- based on patterns and conjectures
- angle bisector
- a ray that divides an angle into two adjacent angles that are congruent
- opposite rays
- if C is between A and B, then CA and CB are opposite rays
- angle
- figure formed by the union of two rays with the same initial point
- (line) segment
- consists of two points of the line called endpoints and all points of the line that are between the two points
- point
- has no dimension, can be represented by a dot, is named using capital letters
- line
- extends in one dimension, can be represented by a "straight line" w/ two arrow heads
- counterexample
- an example that proves a statement false
- plane
- extends in two dimensions, can be represented by a shape that looks like a table top or wall
- postulates
- statements that are accepted without proof
- ray
- consists of an initial point (or endpoint) and all points of the line which are on the same side of the initial point
- congruent angles
- angles with the same measure
- congruent segments
- segments with the same length
- intersect
- if two geometric figures (blank) they have one or more points in common
- adjacent angles
- angles that share a common vertex and side but have common interior points
- segment bisector
- a segment, ray, or line or plane that intersects a segment at its midpoint
- theorems
- statements that are proved
