Exploring Trigonometric Ratios
Young scholars 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.
Curated OER
Exploring the Hinge Theorem
Students explore the application of Hinge Theorem. For this geometry lesson, students write inequalities, given two sides of a triangle. They solve problems with triangular inequalities using the proper theorem.
Curated OER
Composition of Reflections
Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.
Curated OER
Exploring Special Lines
Students compare and order numbers. In this geometry lesson, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.
