Geometry unit 7 polygons and quadrilaterals answer key

What is the sum of the angles of a 25 sided polygon?

We are given the question that finds the measure of an interior angle of 25 sided regular polygon . Hence, the sum of all the interior angles of a 25-sided polygon is 4140∘.

What is the formula to find the measure of each interior angle of a regular polygon?

Answer: To find the measure of an interior angle of a regular polygon, we make use of the formula for each angle = (n - 2) × 180 / n. The formula calculated is only valid in cases of regular-sided polygons.

How many sides does the regular polygon with an interior angle measuring 170 have?

Answer and Explanation: The polygon that has an interior angle of 170∘ has 36 sides.

What are polygons and quadrilaterals?

Examples of polygons include a triangle, square, rectangle, or any unnamed shape that is closed in, and has straight sides. A circle is not a polygon. A quadrilateral is a special kind of polygon that has exactly four sides that are all line segments.
