Across
  1. 1. , The coordinate plane is a two-dimension surface formed by two number lines.
  2. 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.
  3. 4. Number , The positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.
  4. 7. , The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane.
  5. 11. , The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane.
  6. 13. , A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
  7. 15. , a perfect cube of a number, is a number that is equal to the number, multiplied by itself, three times
  8. 17. The number which produces a given number when cubed
  9. 18. , Linear pair of angles are formed when two lines intersect each other at a single point.
  10. 20. , Vertical angles are angles opposite each other where two lines cross.
  11. 21. , when two figures have the same shape but their sizes are different, then such figures are called similar figures.
  12. 22. ,The volume of sphere is the amount of space occupied, within the sphere.
  13. 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.
  14. 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.
  15. 28. ,The longest side of a right triangle, opposite the right angle.
  16. 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.
  17. 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.
  18. 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
  19. 37. , One of a pair of angles on opposite sides of a line intersecting two other lines and outside the two intersected lines.
  20. 39. , Dilation is a transformation, which is used to resize the object.
Down
  1. 2. , Pythagorean triples are a2+b2 = c2 where a, b and c are the three positive integers.
  2. 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.
  3. 6. , An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero.
  4. 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.
  5. 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).
  6. 10. , The √ symbol that is used to denote square root or nth roots.
  7. 12. , a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
  8. 14. , Corresponding sides are the sides that are in the same position in any different 2-dimensional shapes.
  9. 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.
  10. 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.
  11. 23. , Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.
  12. 25. Square, The product of a rational number multiplied by itself.
  13. 26. , A number without fractions; an integer.
  14. 30. , Real numbers can be defined as the union of both rational and irrational numbers.
  15. 31. , Translation: Sliding: moving a shape without rotating or flipping it.
  16. 32. , Exactly equal shape and size.
  17. 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.
  18. 35. , Transversal: A line that crosses at least two other lines
  19. 38. , Not expressible as a ratio of two integers and having an infinite and nonrecurring expansion when expressed as a decimal.
