Preliminary SAT (PSAT) Practice Test

To find the sum of the internal angles in a hexagon, we can use the formula for the sum of the internal angles of a polygon, which is given by (n - 2) × 180 degrees, where n is the number of sides.

For a hexagon, n is 6. Substitute this into the formula:

(6 - 2) × 180 = 4 × 180 = 720 degrees.

Thus, the correct answer for the sum of the internal angles of a hexagon is 720 degrees. This means that the choice indicating 1080 degrees does not accurately represent the calculation involved in determining the internal angles of a hexagon.

The process of calculating the angles illustrates the systematic approach required when working with polygon properties, highlighting the importance of knowing the correct formula and applying it to a specific shape.
