Applying Tangents
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...

Particle Models
In this particle model worksheet, young scholars solve and complete 14 various types of problems. First, they find the magnitude of the side or the angle indicated with a question mark for each triangle illustrated. Then, students find...

The Leaning Tower of Pisa
Learners estimate the equation of a line, angle of elevation and depression in this math lesson. They analyze e famous landmark design and make connections to algebra and geometry. They will also generate an equation, model the x and y...

Trigonometric Ratios
Young scholars 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.

ndirect Measurement Technique: Using Trigonometric Ratios
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
Young scholars evaluate the six trigonometric values of a trig function. In this trigonometry instructional activity, students use the Unit Circle to find the values of right triangles and their angles. They identify an angle...

Elevation at its Peak
High schoolers 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.
