While it may seem incredibly obvious to the geometry student that congruent sides make congruent triangles, the proving of this by definition actually takes a bit of work. This exercise steps the class through this kind of proof by...

In this rigid transformation learning exercise, students follow directions to translate, reflect or rotate a figure in a coordinate plane. Examples and explanations are provided at the beginning of the document. This two-page learning...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Your visual geometry learners will appreciate triangle drawings as they model the triangle sum theorem and algebraically solve to find the missing interior angle in a triangle. Practice problems increase in complexity and vary in their...

Students watch the teacher draw on the chalkboard and try to determine the form being drawn. They use questions to determine Quadrant #1 of a coordinate plane.

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

In this if-then statements and postulates worksheet, 10th graders solve 16 various types of geometry problems that include identifying the hypothesis and conclusions of each conditional statement. Then, they write each conditional...

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

In this geometry worksheet, 10th graders determine the answer to a vocabulary questions and then follow the give rules to place the answer in the appropriate place on the crossword grid.   The one page worksheet contains 18...

Students discover which regular polygons can be used to tile a plane.

In this concepts and applications review worksheet, 10th graders solve and complete 40 various types of multiple choice problems. First, they write the equation of a vertical line passing through a point. Then, students find the...

Students find the volume of rectangular prisms.  In this volume lesson, students use a formula to find the volume of rectangular prisms.  They discuss the definition of volume and draw rectangular prisms.  Students...

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

For this math worksheet, middle schoolers look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Seventh graders investigate the concepts related to the geometry of treehouses that focuses on angles that are similar and congruent. They conduct class discussion in terms of looking at three dimensional shapes that are represented in...

Students explore geometry by participating in a pattern identification activity. In this tetrominoes instructional activity, students define the characteristics of congruent and symmetrical shapes. Students practice translating shapes...

In this geometry worksheet, 10th graders solve problems that are based on the theorems associated with perpendicular and angle bisectors of a triangle.  An application on the coordinate plane is included.  The one page...

Transform your lesson on transformations. Learners use given congruent triangles and tracing paper to determine the single transformation that carries one to the other. The concept is extended to combinations of transformations to...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

In this dilations and similarity activity, pupils solve 10 different problems that include various dilations. First, they determine the scale factor of dilations found in the illustrated graphs. Then, everyone determines the coordinates...

Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...

Students identify symmetry in road signs. For this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...
