Additional comment

It can be useful to memorize the squares of integers up to about 20. You probably already know the first 10 or 12 from your memorization of multiplication tables.

  1² = 1, 2² = 4, 3² = 9, 4² = 16, 5² = 25, 6² = 36, 7² = 49, 8² = 64, 9² = 81,

  10² = 100, 11² = 121, 12² = 144, 13² = 169, 14² = 196, 15² = 225, 16² = 256,

  17² = 289, 18² = 324, 19² = 361, 20² = 400

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
