What is a Parallelogram?
Note:
A parallelogram is a special type of quadrilateral with some special properties. In this tutorial, take a look at parallelograms and learn what kinds of quadrilaterals can also be called parallelograms!
Background Tutorials
-
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.
-
What is a Rectangle?
A rectangle is one of the many fundamental shapes you'll see in math. Rectangles have special properties that can be very useful in helping you solve a problem. This tutorial introduces you to rectangles and explains their interesting qualities!
-
What is a Quadrilateral?
The term quadrilateral is a really fancy sounding name for a certain kind of polygon. Did you know that there are special types of quadrilaterals? Watch this tutorial to learn about quadrilaterals and their special types.
-
What is a Rhombus?
A rhombus is a special kind of quadrilateral. Knowing about the special properties of a rhombus is important to identifying and using these special polygons. This tutorial introduces you to the rhombus and explains its unique qualities. Take a look!

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
-
What are Acute, Obtuse, Right, and Straight Angles?
Did you know that there are different kinds of angles? Knowing how to identify these angles is an important part of solving many problems involving angles. Check out this tutorial and learn about the different kinds of angles!

-
Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.
-
What is a Polygon?
Got a closed figure with three or more sides? Then you have a polygon! In this tutorial, you'll learn about the properties of a polygon, see the names of the most popular polygons, and learn how to identify polygons. Check it out!

-
Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
-
What Does Congruent Mean?
If two figures have the same size and shape, then they are congruent. The term congruent is often used to describe figures like this. In this tutorial, take a look at the term congruent!

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.

How Do You Classify Quadrilaterals?
Got a figure with four sides? Then you have a quadrilateral! But there are many special types of quadrilateral. Follow along as this tutorial shows you how to figure out the possible names for a given quadrilateral!

-
Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
-
How Do You Find the Area of a Parallelogram?
Looking for the area of a parallelogram? Got the length of the base and the height? Then plug those values into the formula for the area of a parallelogram and solve. This tutorial takes you through the process!
-
What is the Formula for the Area of a Parallelogram?
Parallelograms and rectangles are pretty similar. In fact, you can turn a parallelogram into a rectangle to find the formula for the area of a parallelogram! Check out this tutorial to see how it's done!
