An answer key is a document that contains the correct answers to all the questions asked in the test. It helps students to evaluate their performance and identify their strengths and weaknesses. In this article, we will provide you with the answer key for the Unit 8 Polygons and Quadrilaterals test.

## What are Polygons and Quadrilaterals?

Polygons and quadrilaterals are two-dimensional figures that are commonly studied in geometry. A polygon is a closed figure with three or more straight sides, while a quadrilateral is a polygon with four sides. Some examples of polygons include triangles, rectangles, pentagons, and hexagons. Some examples of quadrilaterals include squares, rectangles, rhombuses, and trapezoids.
