7.1-7.5 TEST GEOMETRY

Front

What is the formula to find the sum of the interior angles of a regular polygon?

Back

(n - 2) * 180, where n is the number of sides.

Front

What is the formula to find one exterior angle of a regular polygon?

Back

360 / n, where n is the number of sides.

Front

What is the value of the sum of the interior angles of a polygon with 8 sides?

Back

(8 - 2) * 180 = 1080 degrees.

Front

If a regular polygon has 10 sides, what is the measure of one exterior angle?

Back

360 / 10 = 36 degrees.

Front

What is a midsegment in a trapezoid?

Back

A midsegment is a line segment that connects the midpoints of the non-parallel sides of a trapezoid.

Front

How do you calculate the length of the midsegment of a trapezoid?

Back

It is half the sum of the lengths of the two bases: (Base1 + Base2) / 2.

Front

If the bases of a trapezoid are 8 and 20, what is the length of the midsegment?

Back

(8 + 20) / 2 = 14.

Front

What is the relationship between the number of sides and the sum of the interior angles in a polygon?

Back

The sum of the interior angles increases as the number of sides increases.

Front

What is the measure of each interior angle in a regular polygon with 6 sides?

Back

(6 - 2) * 180 / 6 = 120 degrees.

Front

What is the difference between interior and exterior angles in polygons?

Back

Interior angles are inside the polygon, while exterior angles are formed outside the polygon by extending one side.
