- 2. theoretical The likelihood of an event happening that is based on theory rather than on experience and observation.
- 3. A closed plane figure whose sides are straight lines and do not cross.
- 4. Forming a right angle.
- 6. Any of the four regions formed by the axes in a rectangular coordinate system.
- 8. (relationship) A predictable or prescribed sequence of numbers, objects, etc. Patterns and relationships may be described or presented using munipulatives, tables, graphics (pictures or drwings), or algebraic rules (functions).
- 9. The likelihood of an event happening. An impossible event has a probability of zero. An event that will occur with absolute certainty is assigned a probability of one. Every event that is neither certain nor impossible has a probability that is between zero and one, and is obtained by dividing the number of favorable outcomes of an event by the total number of possible outcomes.
- 10. Any whole number with only two factors, 1 and itself (e.g., 2, 3, 5, 7, 11, etc.).
- 12. A special-case ratio in which the second term is always 100. The ratio is written as a whole number followed by a percent sign (e.g., 25% means the ratio of 25 to 100).
- 13. An undefined, two-dimensional (no depth) geometric surface that has no boundaries specified. A plane is determined by defining points or lines exisiting on the plane.
Down
- 1. The square of the hypotenuse (c) of a right triangle is equal to the sum of the square of the legs (a and b), as shown in the equation c^2=a^2+b^2.
- 2. The symbol designating the ratio of the circumference of a circle to its diameter, represented as either 3.17 or 22/7.
- 3. The length of the boundary around a figure.
- 4. section The intersection of a plane and a three-dimensional figure.
- 5. A two-dimensional figure that lies entirely within a single plane.
- 7. A set of steps that demonstrates the truth of a given statement. Each step can be justified with a reason, such as a given, a definition, an axiom, or a previously proven property.
- 9. The position of a single digit in a whole number or decimal number containing one or more digits.
- 11. sign The symbol used before a number to show that the number is radicand.
- 12. A location in space that has no length or width.
- 13. A three-dimensional figure (polyhedron) with congruent polygonal bases and lateral faces that are all parallelograms.
