Applying Tangents

For Students 9th - 10th Standards
What does geometry have to do with depression? It's an angle of course! Learners apply the tangent ratio to problem solving questions by finding missing lengths. Problems include angles of elevation and angles of depression. Pupils make...

ndirect Measurement Technique: Using Trigonometric Ratios

For Teachers 9th
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...

Right Triangles and Unit Circles

For Teachers 9th - 11th
Learners evaluate the six trigonometric values of a trig function. In this trigonometry lesson, students use the Unit Circle to find the values of right triangles and their angles. They identify an angle of elevation and...

Elevation at its Peak

For Teachers 9th - 12th
Students pretend they are hiking up a mountain. They practice making calculations on angles and elevation. They use topographic maps to estimate distances and trigonometric ratio methods.
