  1. 2. / two figures that are said to be similar if they are the same shape. THey are only considered similar when their corresponding angles are congruent.
  2. 4. / a line that just touches a curve at a point, matching the curve's slope there.Leibniz defined it as the line through a pair of infinitely close points on the curve.
  3. 5. / a nonnegative number equal in numerical value to a given real number.The positive square root of the sum of the squares of the real and imaginary parts of a complex number.
  4. 8. /a way of expressing numbers that are too large or too small to be conveniently written in decimal form.Where a number is written in two different parts.first, just the digits (with the decimal point placed after the first digit)Followed by: ×10 to a power that will put the decimal point back where it should be.
  5. 11. / an equation where the variables represent known values.Consists primarily of letters, and formulas can be used as an example for this equation.
  6. 13. / changing a shape using turn,flip, slide,or resize. After any of those, the shape still has the same size,area,angles,and line lengths.
  7. 15. / a symbol and placeholder for a quantitiy that may change.It may represent a number, vector,a matrix,a function,the argument of a function, a set, or an element of a set.Often known as "x".
  8. 17. / an exponent that can be a fraction.represents both an integer exponent and an nth term.
  9. 18. / two lines on the same plane that never intercept, no matter how far they keep going.These can be represented in the real world by showing them through train tracks.
  10. 19. / the difference between each number in an arithmetic sequence. the sequence {1, 4, 7, 10, 13,...} is made by adding 3 each time, so 3 is the ( ).
  11. 20. / is a flip-over-the-line reflection. The preimage and image are congruent, but they are mirrored images of each other.

  1. 1. / a line that passes through two lines in the same plane at two distinct points.When this line goes through two parallel lines, angles are formed where they connect.
  2. 3. / a scalar value that is a function of the entries of a square matrix.Allows characterizing some properties of the matrix and the linear map represented by the matrix.
  3. 6. / a set of numbers arranged in rows and columns so as to form a rectangular array.Used to represent a mathematical object or a property of such an object.
  4. 7. / turns the preimage around a fixed point, called the center of rotation. The center of rotation may be any point, including the origin or a point on the preimage
  5. 9. / is a transformation that moves all points of a figure by the same distance in a given direction. Sometimes we call these shifts or slides.
  6. 10. / a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. Example 2, 4, 8, 16, 32, 64..
  7. 12. / in a right angled triangle the ( ) of an angle is the length of the adjacent side divided by the length of the hypotenuse.
  8. 14. / a sequence in which the difference between any two terms is constant. when you take any number in the sequence then subtract it from the previous one, and the result is always the same or constant.
  9. 16. / a set of numbers with a particular pattern or function. Each number is called a term.
