In this math learning exercise, students find the solutions to the missing angles and sides of the triangles using the correct trigonometric ratios.

In this geometric shapes worksheet, students count how many triangles, rectangles, and circles they see and write down the numbers in the boxes provided.

In this math worksheet, students examine the two triangles and they compare them to each other. The shapes are measured and labeled as comparable to each other.

In this geometry worksheet, students choose the correct name to match the shape given. Students identify the words for oval, rectangle, square, circle, triangle, and diamond.

In this shapes worksheet, students color all the big shapes blue, the middle sized shapes yellow and the small sized shapes red. Then they cut out all the shapes and sort them from big to small.

Students explore the difference between drawing and constructing a triangle utilizing The Geometer's Sketchpad on the computer. They create, develop and script constructions for both isosceles and equilateral triangles. Each student has...

Students engage in a study of the Pythagorean Theorem to classify the hypotenuse of a triangle. The teacher uses examples from the activity to aid students in comprehension of solving problems that involve problem solving. They create a...

Seventh graders participate in a lesson that is focused upon the concepts of classifying different angles and triangles. They practice classifying triangles according to its kind that includes types of angles, congruence, and vertices....

Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

Students review basic shapes, such as circles, squares, triangles, and rectangles, find objects in those shapes in classroom, watch Clifford's Fun with Shapes video, practice reproducing four shapes, and rotate through four classroom...

Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Learners explore about triangles and the simple machines that are made from those triangles. They are able to identify the kinds of triangles in the machines, tell how the triangular shapes make the machines function, and build a simple...

Fifth graders explore Pythagoras' Theorem. They examine the pattern linking the length of the hypotenuse of a right angled triangle and the length of the other two sides. Students find an unknown side in right angled triangles.

Fifth graders explore the importance of triangles in the real world. They find the unknown side of a right triangle using a scale drawing. Students use Pythagoras' Theorem and other appropriate ratios.

Fourth graders use two different techniques to construct triangles with specific dimensions. They determine how to construct nets for three-dimensional objects focusing on those made with equilateral triangles. They are able to name the...

Young scholars are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Students build on existing knowledge of median and midpoints of triangles. They incorporate their prior knowledge to develop an example of the center of a mass of a triangle. They share their sketches with their classmates.

Students are introduced to the Pythagorean theorem. They use three different activities that give students the opportuntiy to observe triangles, and use the Pythagorean theorem and practice different ways of determining areas of...

Students explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.

Twelfth graders apply perimeter measurement to items found in newspapers and calculate the cost in terms of feet or yards. They share answers and explanations with classmates.

Students explore how the Pythagorean Theorem works and how to apply it.

Pupils are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

In this triangles activity, high schoolers solve 1 problem of multiple variables within a single picture of various triangles intersecting with a pair of parallel lines.

In this Geometry instructional (work)sheet, students are instructed on how to find the geometric mean.  Students are then shown how the geometric mean is applied to proving similar triangles.
