MATHEMATICS 8 VOCABULARY
Across
- 4. A group of points in a scatter plot that are near each other.
- 6. like terms: Using the distributive law to add any two multiples of an expression such as x. For example, you can simplify 4x+5x into 9x.
- 8. law of multiplication: For two numbers a and b, a(b)=b(a).
- 9. The distance around an entire figure, such as a circle or a sphere. For a sphere, this means the distance around a circle on the sphere whose center is at the center of the sphere.
Down
- 1. A constant that a variable or expression is multiplied by.
- 2. A solid figure formed by taking a flat circular disk and extending it up to a single point.
- 3. relative frequency: A joint frequency divided by the total of its row or column in a two-way frequency table.
- 4. The same shape and size. Two plane figures are congruent if one can be obtained from the other by a rigid motion (a sequence of translations, rotations, and reflections).
- 5. rule: A rule that allows you to tell that two figures are congruent by looking at some of their measurements, such as the Side-Angle-Side (SAS), Angle-Side-Angle (ASA), and Side-Side-Side (SSS) rules for triangles.
- 7. law of addition: For any two numbers a and b, a+b=b+a.
