What is a Trapezoid?
Note:
A trapezoid is a special type of quadrilateral with some special properties. This tutorial introduces you to trapezoids and gives you a look at the special properties needed for a quadrilateral to be called a trapezoid. Check it out!
Background Tutorials
-
Derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines
-
What are Parallel Lines?
Lines that are parallel have a very special quality. Without this quality, these lines are not parallel. In this tutorial, take a look at parallel lines and see how they are different from any other kind of lines!
-
-
Investigate patterns to make conjectures about geometric relationships, including angles formed by parallel lines cut by a transversal, criteria required for triangle congruence, special segments of triangles, diagonals of quadrilaterals, interior and exterior angles of polygons, and special segments and angles of circles choosing from a variety of tools
-
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!

-
Prove a quadrilateral is a parallelogram, rectangle, square, or rhombus using opposite sides, opposite angles, or diagonals and apply these relationships to solve problems
-
What is a Parallelogram?
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!
-
Further Exploration
-
Determine the area of composite two-dimensional figures comprised of a combination of triangles, parallelograms, trapezoids, kites, regular polygons, or sectors of circles to solve problems using appropriate units of measure

How Do You Find the Area of a Trapezoid?
Want to find the area of a trapezoid? If you have the length of each base and the height, you can use them to find the area. In this tutorial, you'll see how to identify those values and plug them into the formula for the area of a trapezoid. Then see how to simplify to get your answer!
-
What is the Formula for the Area of a Trapezoid?
Trying to figure out the formula for the area of a trapezoid? You could start by creating a parallelogram out of two trapezoids. Then, use the formula for the area of a parallelogram to figure out the formula for the area of one trapezoid. This tutorial shows you how!
