General Information
Test Item Specifications
Students will determine the measures of interior and exterior angles of polygons.
All angle measurements will be in degrees.
Items may be set in either real-world or mathematical contexts.
Graphics should be used in these items, as appropriate.

Test Item # | Question | Difficulty | Type |
Sample Item 1 | A regular hexagon and a regular heptagon share one side, as shown in the diagram below. Which of the following is closest to the measure of x, the angle formed by one side of the hexagon and one side of the heptagon? |
N/A | MC: Multiple Choice |
Sample Item 2 | Claire is drawing a regular polygon. She has drawn two of the sides with an interior angle of 140°, as shown below. When Claire completes the regular polygon, what should be the sum, in degrees, of the measures of the interior angles? |
