Note to Remember:

  • A dot can be used to symbolize a position as a point. A point has a position; it has no length, width, shape, or size.
  • A line is formed when two separate points are joined.
  • Acute angles are less than 90 degrees.
  • The right angles are 90 degrees.
  • Obtuse angles are greater than 90 degrees.
  • Straight angles are 180 degrees.
  • The complementary angle has a sum of 90 degrees.
  • Supplementary angles have a sum of 180 degrees.


Write A if the figure is an angle and determine what kind of angle it is. Write L if it is a line and P if it is a point.
