  • Find the number of sides of a regular polygon with 18° as the exterior angle.
    20 sides
  • Will a regular hexagon tessellate with itself?
    Yes, because the interior angles of a regular hexagon are all 120°, so when three hexagons are put together they make an angle of 360°, there will be no gaps.
  • The measure of one exterior angle of a regular polygon is 72°. Find the number of sides.
    n=5
  • A(4,5) B(10,-8) Find the horizontal and vertical distance.
    Horizontal = 6 Vertical = 13
  • Will a regular pentagon tessellate? Explain your answer.
    No, as angles do not add up to 360° when placed together.
  • What is the sum of the exterior angles of a 100-gon?
    360°
  • The measure of an exterior angle of a regular polygon is 2x, and the measure of an interior angle is 4x. Find the measure of one interior and exterior angle
    Ex-60°  In-120°
  • Interior angle plus exterior angle is equal to
    180°
  • Will a regular pentagon tessellate? Explain your answer.
    No, as angles do not add up to 360° when placed together.
  • Will a regular pentagon tessellate? Explain your answer.
    No, as angles do not add up to 360° when placed together.
  • A pattern made by fitting shapes together, with no spaces and overlapping.
    Tessellations
  • If the sum of the measures of six angles of a heptagon is 864°, the the measure of the seventh angle is ....
    36°
  • What is the sum of the interior angle of a nonagon?
    1260°
  • The measure of one interior angle of a regular polygon is 144°. How many sides does it have?
    n=10
  • What is sum of the exterior angles of any polygon?
    360°
  • Why 4180 cannot be the sum of the interior angles of a polygon?
    4180 is not a multiple of 180
  • Find the measure of an interior and an exterior angle of a regular 24-gon. Both answers need to be correct.
    In=165°   Ex =5°
  • A polygon has n sides. What would be the sum of the interior angles of this n-sided polygon?
    180(n-2)
  • A polygon whose interior angles have a sum smaller than the sum of its exterior angles is a ____________________.
    Triangle
  • Will a regular pentagon tessellate? Explain your answer.
    No, as angles do not add up to 360° when placed together.
  • What is the measure of each interior angle of a regular 45-gon?
    172°
  • Which polygon has angles which have a sum of 2520°
    16-gon
  • Is it possible to have a regular polygon whose each interior angle is 110°
    Not possible
