- b Lines that meet at 90° angles.
- c An example that shows a conjecture to be incorrect or a definition to be inadequate.
- d A triangle with three acute angles.
- e An undefined term thought of as a location with no size or dimension. It is the most basic building block of geometry. In a two-dimensional coordinate system, its location is represented by an ordered pair of numbers (x, y).

- The length of the boundary of a two-dimensional figure. For a polygon it is the sum of the lengths of its sides.
- A polygon with n sides.
- An undefined term thought of as a flat surface that extends infinitely along its edges. It has length and width but no thickness, so it is two-dimensional.
- A ray that has its endpoint at the vertex of the angle and that divides the angle into two congruent angles.
- The point on a line segment that is the same distance from both endpoints.
