6 - (Review: Circles) - Determining Interior Angles of a Polygon

What is the sum of interior angles in a triangle?

• 180 degrees

• 270 degrees

• 360 degrees

• 90 degrees

How many degrees are there in each angle of a square?

• 90 degrees

• 360 degrees

• 180 degrees

• 45 degrees

What is the formula to calculate the sum of interior angles in a polygon?

• n * 90

• (n-2) * 180

• n * 180

• (n+2) * 180

Using the formula, what is the sum of interior angles for a pentagon?

• 540 degrees

• 360 degrees

• 720 degrees

• 180 degrees

What is the sum of interior angles in a square using the general formula?

• 180 degrees

• 360 degrees

• 720 degrees

• 90 degrees

What is the sum of interior angles for a triangle, as confirmed by the formula?

• 270 degrees

• 90 degrees

• 180 degrees

• 360 degrees

If a polygon is regular, how can you find the measure of one angle?

• Divide the sum of angles by the number of sides

• Multiply the number of sides by 180

• None of the above

• Add 180 to the number of sides

What does it mean if a polygon is described as 'regular'?

• None of the above

• It has an equal number of sides and angles

• It has only right angles

• All sides and angles are equal

For a pentagon, what would be the measure of each angle if it is regular?

• 150 degrees

• 108 degrees

• 120 degrees

• 135 degrees

Can the formula for interior angles be used for irregular polygons?

• None of the above

• Yes, for both sum and individual angles

• No, it cannot be used

• Yes, for sum but not for individual angles
