TLF ID L2334
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.
