How far is that boat from the lighthouse? Scholars create diagrams to represent a scenario given the angle of depreciation from a lighthouse to a boat. Learners apply the basic trigonometric functions to find various distances stemming from either the hypotenuse or an unknown leg of a right triangle.

Instructional Ideas

• Lead a discussion on how to determine whether the description is about the hypotenuse or a leg of the right triangle
• Require the pupils to show their work

Classroom Considerations

• Individuals should understand how to create the right triangles given an angle of depreciation
• Must set up a free account to access the interactive

Pros

• The interactive allows for the creation of all the scenarios in the questions
• Shows the correct answers if wrong answers are given

Cons

• None
