This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...
When are trapezoids better than rectangles? Using trapezoids pupils approximate the area of fabric defined by a function. Just like with rectangles, learners realize the more trapezoids the more accurate the approximation. Scholars use...

Enjoy this nicely organized worksheet that puts together multiple problems regarding trapezoid proofs. The resource can be used as a guide that begins with proving properties and ends with solving for measures of line segments.
Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...
In this online math worksheet, students practice finding the area of a trapezoid, given the height and length, This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A...
Here is a straightforward example of how to apply the Pythagorean Theorem to find an unknown side-length of a trapezoid. Commentary gives additional information on proving that the inside of the trapezoid is a rectangle, but is...
After a tornado, an insurance company is in need of finding the area of a plot of land. Pupils use their knowledge of trapezoids and area formulas to calculate the area of the plot of land. The scholars work in groups to justify the...
Everything will add up. Learners find the areas of trapezoids, kites, and rhombi by using the area formulas. Scholars find any missing information needed to use within the formula and continue to use prior knowledge and practice...
Students determine the missing vertices of quadrilaterals. In this rectangles and trapezoids instructional activity, students examine the characteristics of quadrilaterals. They identify the missing vertices of a quadrilateral on a...

In this trapezoid worksheet, students examine given data and compute the area of trapezoids. They identify the base and height of each figure. This one-page worksheet contains 18 problems. Answers are provided.
In this geometry worksheet, 10th graders determine the area of triangles, parallelograms, trapezoids, kites, and rhombuses. The one page worksheet contains eleven problems. Answers are included.
What polygon is this? Young geometers categorize shapes by circling all the quadrilaterals in a set of figures. Next, they write the names of 10 polygons using a visual guide as reference. Review the guide together before they start if...
Scholars examine six common quadrilaterals and identify each by writing its name beneath the shape. Next, they sketch four shapes: parallelogram, rectangle, rhombus, and trapezoid. Once finished, review which features helped learners...
In this online math worksheet, students must find the missing measurement in a variety of trapezoids. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific...
High schoolers answer two problems involving area of shaded regions. Students then answers six questions involving perimeter, area, and circumferences. The remaining two questions involve ratios of similar figures.
In this trapezoids worksheet, 10th graders solve 5 different problems related to trapezoids and applying the appropriate theorem. First, they define a trapezoid, including its bases, legs, and base angles. Then, students use the...
Students are given patterns of trapezoids and are to calculate the area of one trapezoid by using both patterns. They should form a parallelogram and calculate the area. They practice this technique until there is understanding.
