Solve measurement problems involving right-angled triangles by using similar triangles and trigonometric methods, including tangent values. Identify corresponding sides and ratio relationships in similar triangles. Solve measurement problems by using tangent values to calculate side lengths in triangles. For example, find the width of a river, given one angle and distance along the riverside. This learning object is one in a series of ten objects.
Objective
1. Students apply knowledge of relationships between sides of similar triangles to calculate side lengths in right-angled triangles.
2. Students use multiplicative and ratio strategies to solve measurement problems.
