Pupils display knowledge of line of symmetry by designing a geometric stained glass window pattern.

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...

Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

In this geometry worksheet, 10th graders determine that if two planes are perpendicular to the same line, then they are parallel.  The one page worksheet contains one problem with the solution. 

Students graph linear equations and then find the person in class whose linear equation graph is perpendicular to theirs. In this graphing inequalities lesson plan, students graph their perpendicular slopes and then once their find their...

In this geometry worksheet, learners identify the missing angles formed by parallel lines and a transversal. They differentiate between parallel and perpendicular lines. There are four questions.

Students investigate the properties of lines and congruent triangle theorems as well as apply geometric properties and relationships to real-world mathematical problems. Given two different scenarios, they examine maps that have been...

In this math worksheet, students write linear equations in slope-intercept form that passes through the given point. On the last 8 equations, students write the equation of the perpendicular line.

Pupils define slope, and practice finding the slope of lines through given points. They determine the angle of inclination. Students find the relationship between the slope and the tangent of the lines. Pupils determine special...

Students will determine the relationship between two line segments in a given three-dimensional figure. Figures are either rectangular or triangular prisms.

Tenth graders construct a variety of geometric shapes and designs using a Mira, Clinometer and Geometry Flash Cards. They complete a worksheet.

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

Geometry is full of shapes, figures, and corresponding things here and there. The guide shares all of the key pieces of geometric information in a nicely color-coded and labeled sheet. 

Students explore the concept of quadrilaterals. In this quadrilaterals lesson plan, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

In this quadrilaterals worksheet, 10th graders solve and complete 10 different problems that include identifying various quadrilaterals. First, they indicate whether the statements are true or false for each. Then, students determine the...

In this motions in geometry worksheet, students draw translations, rotations, and reflections. This three-page worksheet contains examples, instructions, and 6 problems. The last page contains answers.

Students build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Students then switch with a partner to try an make a symmetrical shape.

In this geometry worksheet, 10th graders construct parallel and perpendicular lines using a compass and a straight edge. There are 4 construction questions with an answer key.

In this geometry worksheet, 10th graders solve problems using parallel chords, perpendicular bisectors and chords that are equal distance from the center.

Students explore Geometry with Twizzlers Candy, pipe cleaners, paper, pencils, and protractors. They manipulate these items to create different angles introduced by the teacher.

In this angle measurement worksheet, 10th graders solve 24 different problems related to determining the measurement of various angles. First, they define the various ways to measure an angle and define the type of angle that it is....
