Students 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.

Young scholars calculate the different ratios using a right triangle. In this trigonometry lesson, students identify the sine, cosine and tangent of each side. They find the missing angles using the different ratios.

Students examine how to apply the principles of trigonometry in authentic measurement situations. They work in groups to determine the height of an object such as a flag pole by determine the angle from their position to the top.

Students explore geometry by using computer applications. In this spatial measurement lesson, students discuss the difference between area, weight, volume and other forms of measurement. Students utilize computer applications to find the...

In this polygons worksheet, students classify each polygon in as many was possible. Students then write polygon or not a polygon to classify each figure. Students find the measure of the missing angles and complete two test prep...

Third graders search for and locate examples of acute, right, straight and obtuse angles in the classroom. They record their findings by writing the exact location of each angle found and organize them into angle categories.

Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...

Eighth graders find the length of the third side of a right triangle.

Pupils study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.
