Use the diagram below to classify abcd

Square

Step-by-step explanation:

Well, the options they have given you to choose from are a pentagon, a quadrilateral and a square. Let's first take a look at these options and eliminate which ones can't be possible. The first option, a pentagon, can be eliminated from the possibilities because a pentagon has five sides and figure ABCD has only four sides. The second option, quadrilateral, is true because a quadrilateral has four sides and so does figure ABCD. But, if you look at the third option, a square, this is the best way out of all the options to classify this figure because there are three things ALL squares must have:

- four sides

- all right angles

- all the sides MUST be equal

Knowing this, taking a look at the picture, you will see that there are indeed four right angles, four sides AND all congruent sides, proven by the four triangles inside the square. The answer isn't quadrilateral because, although that may be true, there are MANY types of quadrilaterals, trapezoids, rectangles, rhombuses and so on, each having different properties and characteristics. Therefore, the third option, SQUARE is the right answer.
