Students investigate the Pythagorean triples. In this geometry lesson, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.

Students solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.

In this congruent figures learning exercise, students answer ten true or false questions. A sample question reads: "Two triangles are congruent when their shape and size will be the same."

Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

Learners identify the ratios of trig functions. In this trigonometry lesson, students construct triangles and use it to derive the values of sine, cosine and tangent. They use Cabri software to create the visual of the identities.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.
