Math Vocabulary
Across
- 1. , The coordinate plane is a two-dimension surface formed by two number lines.
- 3. , The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
- 4. Number , The positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.
- 7. , The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane.
- 11. , The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane.
- 13. , A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
- 15. , a perfect cube of a number, is a number that is equal to the number, multiplied by itself, three times
- 17. The number which produces a given number when cubed
- 18. , Linear pair of angles are formed when two lines intersect each other at a single point.
- 20. , Vertical angles are angles opposite each other where two lines cross.
- 21. , when two figures have the same shape but their sizes are different, then such figures are called similar figures.
- 22. ,The volume of sphere is the amount of space occupied, within the sphere.
- 24. , Expressible, or containing quantities that are expressible, as a ratio of whole numbers. When expressed as a decimal, a rational number has a finite or recurring expansion.
- 27. , A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
- 28. ,The longest side of a right triangle, opposite the right angle.
- 29. , Two angles that are exterior to the parallel lines and on the same side of the transversal line are called same-side exterior angles. The theorem states that same-side exterior angles are supplementary, meaning that they have a sum of 180 degrees.
- 33. Pair) , An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
- 36. A quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression
- 37. , One of a pair of angles on opposite sides of a line intersecting two other lines and outside the two intersected lines.
- 39. , Dilation is a transformation, which is used to resize the object.
Down
- 2. , Pythagorean triples are a2+b2 = c2 where a, b and c are the three positive integers.
- 5. , Alternate exterior angles are the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal.
- 6. , An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero.
- 8. of Symmetry) , Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one half is the mirror image of the other half.
- 9. , A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
- 10. , The √ symbol that is used to denote square root or nth roots.
- 12. , a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
- 14. , Corresponding sides are the sides that are in the same position in any different 2-dimensional shapes.
- 16. , A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
- 19. , Same side interior angles are two angles that are on the interior of (between) the two lines and specifically on the same side of the transversal.
- 23. , Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.
- 25. Square, The product of a rational number multiplied by itself.
- 26. , A number without fractions; an integer.
- 30. , Real numbers can be defined as the union of both rational and irrational numbers.
- 31. , Translation: Sliding: moving a shape without rotating or flipping it.
- 32. , Exactly equal shape and size.
- 34. Theorem , Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
- 35. , Transversal: A line that crosses at least two other lines
- 38. , Not expressible as a ratio of two integers and having an infinite and nonrecurring expansion when expressed as a decimal.
