In this lesson, students will study the different types of quadrilaterals, focusing on their commonalities and distinctions. Students will:

- identify and describe the attributes of quadrilaterals.
- classify quadrilaterals based on characteristics into subcategories of quadrilaterals, including parallelograms, rectangles, rhombi, squares, and trapezoids.

- How can patterns be used to describe relationships in mathematical situations?
- How can recognizing repetition or regularity assist in solving problems more efficiently?
- How can the application of the attributes of geometric shapes support mathematical reasoning and problem solving?
- How can geometric properties and theorems be used to describe, model, and analyze situations?
- How are spatial relationships, including shape and dimension, used to draw, construct, model, and represent real situations or solve problems?

**Pentagon:**A polygon with exactly five sides.**Polygon:**A closed plane figure bounded by three or more line segments**Quadrilateral:**A polygon with exactly four sides.**Rhombus:**A quadrilateral with sides of equal length.
