Question 1: Angles of a regular polygon are not equal. True or False

Answer:

False. Regular polygons have angles with congruent measurements.

Question 2: 12 sided shape

Answer:

dodecagon Question 3: Explain how to use the number of sides to find one angle measure of a regular polygon.

Answer:

(n-2) x 180 = the sum of the interior angles of a polygon. Divide this number by the number of sides.

Question 4: What is the measure of one angle of a regular nonagon?

Answer:

140 degrees

Question 5: Sum of the interior angles of a polygon

Answer:

(n-2) x 180 where n is the number of sides on the polygon

Question 6: 8 sided shape

Answer:

octagon Question 7: Why is it important to know if a polygon is regular or irregular when determining angle measurements?

Answer:

With regular polygons you can use the rule (n-2)x180/n. With irregular polygons you cannot use this rule because the angles are not congruent.

Question 8: equilateral triangle

Answer:

A triangle with three congruent sides; all side lengths have the same measure.

Question 9: 11 sided shape

Answer:

hendecagon or an 11-gon

Question 10: 3 sided shape

Answer:

triangle

Question 11: 5 sided shape

Answer:

pentagon

Question 12: 4 sided shape

Answer:

quadrilateral

Question 13: 6 sided shape

Answer:

hexagon Question 14: Explain how to use the number of sides to find one angle measure of a regular polygon.

Answer:

(n-2) x 180 = the sum of the interior angles of a polygon. Divide this number by the number of sides.

Question 15: 7 sided shape

Answer:

septagon or heptagon

Question 16: Triangulate or Triangulation

Answer:

The process of dividing a polygon into triangles by drawing its diagonals

Question 17: Find the measure of one interior angle for a regular octagon

Answer:

135 degrees Question 18: A regular pentagon and an irregular pentagon both have the same total interior angle measurement. True or False

Answer:

True. It does not matter if a polygon is regular or irregular. The interior angle measure is always the same.

Question 19: What is the easiest way to triangulate a polygon?

Answer:

Start from one vertex to draw non-intersecting diagonals.

Question 20: right triangle

Answer:

A triangle with one 90 degree angle.

Question 21: Find the sum of the interior angles of a decagon.

Answer:

1440 degrees

Question 22: obtuse

Answer:

A triangle with one obtuse angle; one angle measure is greater than 90 degrees.

Question 23: 15 sided shape

Answer:

pentadecagon Question 24: Find the measure of one interior angle for a regular 12 sided figure.

Answer:

150 degrees

Question 25: Find the sum of the interior angles of a 18-gon.

Answer:

2880 degrees

Question 26: What is the measure of one angle of a regular hexagon?

Answer:

120 degrees

Question 27: Polygon

Answer:

A closed plane figure created by three or more line segments that intersect only at their endpoints (vertices) Question 28: Regular polygons have both congruent sides and congruent angles. True or False

Answer:

True. Regular polygons have congruent angles and sides.
