1. a Two points on a circle and the continuous part of the circle between them.
2. b Lines that meet at 90° angles.
3. c An example that shows a conjecture to be incorrect or a definition to be inadequate.
4. d A triangle with three acute angles.
5. 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).

### 5 Multiple choice questions

1. The length of the boundary of a two-dimensional figure. For a polygon it is the sum of the lengths of its sides.
2. A polygon with n sides.
3. 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.
4. A ray that has its endpoint at the vertex of the angle and that divides the angle into two congruent angles.
5. The point on a line segment that is the same distance from both endpoints.
