Solve measurement problems involving right-angled triangles by using similar triangles and trigonometric methods, including sine values. Identify corresponding sides and ratio relationships in similar triangles. Solve measurement problems by using sine values to calculate the length of a hypotenuse in triangles. For example, find the length of a ladder needed to reach the top of a castle, given its angle to the ground and the height of the castle. 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.
