Across
- 2. The lowest number a set of numbers can be multiplied to get. Can be found listing out multiples of the numbers in a set, and finding the first shared number.
- 5. A trigonometric ratio in which the adjacent side of θ is divided by the hypotenuse of a right triangle. It can be used to find both side lengths and angles.
- 10. Positive numbers that don’t involve fractions and/or decimals. Includes the number 0.
- 11. The biggest whole number that can be divided into a set of numbers. Can be found by breaking down each number in a set to all its prime numbers.
- 14. In a geometric sequence, it is the constant multiplication between the numbers in a sequence. Can be found by dividing a term by its predecessor.
- 18. A figure that has been moved across a coordinate grid up, down, left, or right. The figure will stay congruent after the change.
- 19. A positive or negative number that is never ending and never repeats. It cannot also be expressed as a fraction with simple integers.
- 20. Positive whole numbers that don’t include fractions and/or decimals. Excludes the number 0.
Down
- 1. Two or more lines that follow the same path on a coordinate plane. When letting them run straight forever, they will never intersect.
- 3. Taking a base number and adding a constant number to it multiple times. The sequence can last forever.
- 4. In an arithmetic sequence, it is the constant rate of change between the previous term throughout the whole sequence. Can be found by subtracting a term by its predecessor.
- 6. An equation used to find the middle point between two points on a graph. Expressed as (x1 + x2)/2, (y1 + y2)/2.
- 7. Sides in a right triangle that are proportional to each other. They include: Sine, Cosine, and Tangent.
- 8. The trigonometric ratio that can be found by taking the opposite of θ divided by the hypotenuse of a right triangle. It can be used to find the angle measure or side length.
- 9. Showing a number being multiplied by itself 0 times in the form of an exponent. Is always equal to 1.
- 12. The process of taking a number and multiplying it by itself a number of times. Expressed as a smaller number atop the base number.
- 13. The process of taking two sides of a right triangle and finding the third one. Expressed as a^2+b^2=c^2.
- 15. Two shapes who both possess the same number of sides, angle measures for the respective sides and whose side lengths are proportional. The proportionality can be found by dividing one side by its respective counterpart for all sides and seeing if they are equal.
- 16. The equation used to find the distance between two points on a coordinate plane. Expressed as √[(x₂ - x₁)² + (y₂ - y₁)²].
- 17. The longest side of a right triangle that is opposite of the right angle. Can be found using the pythagorean theorem.
