Quadrilaterals Reference Chart

About this resource

What's inside this resource

Six quadrilaterals — square, rectangle, parallelogram, rhombus, trapezoid, and kite — are laid out on a single reference chart, each labeled with its defining properties for side length, side parallelism, and interior angles. The square's entry states all four sides are equal, opposite sides are parallel, and all interior angles are 90°, while the rectangle shares the equal-and-parallel and 90°-angle properties without requiring equal side lengths. The rhombus mirrors the square's side properties but lists equal opposite angles rather than 90° angles, and the trapezoid and kite are distinguished by having only one pair of parallel sides or one pair of equal opposite angles, respectively. The chart appears on both pages of the file. There is no student worksheet, question set, or answer key — it functions as a lookup reference rather than a graded task.

Quadrilaterals Reference Chart
Understanding polygons has never been easier. This reference chart provides a clear, organized view of the main types of polygons, helping students identify and compare them based on their sides, angles, and special properties. The chart comes in a full-color version, which works beautifully on classroom walls, whiteboards, or even for digital displays. There is also a black-and-white version, perfect for student binders, interactive notebooks, or individual study sheets, so students can have a handy reference at their desks.

This resource is great for lessons on 2D shapes and polygons classification. It is especially helpful for visual learners who benefit from seeing concepts illustrated clearly, and it can enhance math centers, classroom displays, or study materials. Using the chart regularly helps students build confidence in recognizing and naming different polygons types while reinforcing essential geometry vocabulary. Teachers will also appreciate the convenience, since the chart is ready to print and use immediately. It is best suited for students in grades 3 through 6, but it can also serve as a useful review for older students. Whether displayed in color on the math wall or printed in black-and-white for student reference, this chart is a flexible and practical addition to any geometry unit or STEM resource collection.

In the classroom

Teaching tips & learning objectives

Learning objectives

Students will identify a quadrilateral (square, rectangle, parallelogram, rhombus, trapezoid, or kite) from its listed side and angle properties.
Students will compare two quadrilaterals by the properties they share and the properties that differentiate them (e.g., square vs. rectangle, square vs. rhombus).

Teaching tips

Post the chart at eye level near the classroom's geometry wall so students can check the six quadrilateral definitions while working other tasks.
Use the shared and differing properties — squares and rectangles both list four 90° interior angles, while squares and rhombuses both list four equal sides — to prompt a compare-and-contrast discussion rather than isolated memorization.
Introduce the chart at the start of a quadrilateral-classification unit, since it functions as a lookup reference rather than a graded task.

Skills covered

Quadrilateral property recognition — matching a shape to its defining side-length, parallelism, and angle properties as printed on the chart.
Shape classification reasoning — distinguishing quadrilaterals that share some properties (e.g., squares and rectangles both have four 90° angles) but not others.
Geometry vocabulary — using terms such as parallel, opposite sides, interior angle, and adjacent sides as they appear on the chart.

Good to know

Questions teachers ask about this resource

How does the chart distinguish a square from a rhombus?

Both are listed with four equal sides and parallel opposite sides, but the square's entry also states all interior angles are 90°, a property the rhombus entry does not include.

Curriculum

Standards, concepts & topics

Standards

5.G.B.3 — Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
5.G.B.4 — Classify two-dimensional figures in a hierarchy based on properties.
3.G.A.1 — Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
