Learners identify the different angles and sides of a triangle. In this geometry lesson, students identify the six trigonometric ratios. They graph the graph of each trig function and analyze it.

Students measure distances using indirect measurements. For this geometry lesson, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.

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

After being introduced to the basic trigonometry functions, young scholars calculate the height of school landmarks. They experiment with different angles to find the correct height.

Students measure and analyze angles. In this trigonometry activity, students measure angles and distances use non-traditional techniques. They identify the different ratios of sine, cosine and tangent.

Students study the law of sine and cosine. In this pre-calculus lesson, students create a triangle and identify the different ratios of a non-right triangle. They use the properties of sine and cosine to solve.

Tenth graders identify the trigonometric ratios for right angled triangles. Through independent investigation, they discover the constancy between the ratios of any two sides of similar triangles. In an alternative method, 10th graders...

Students apply the properties of a right triangle. In this triangle lesson, students describe and compare radians to degrees. They solve problems using the properties and ratios of a right triangle.
