Learning Goals
Lesson 5-1: Right Triangle Trigonometry
 I can use the Pythagorean Theorem to solve for an unknown side length of a right triangle.
 I can use the characteristics of similar figures to justify the trigonometric ratios.
 I can define the following trigonometric ratios for acute angles in a right triangle: sine, cosine,
and tangent.
 I can calculate sine, cosine and tangent ratios for acute angles in a right triangle when given two
side lengths.
 I can understand that if cos A = sin B, then A and B are complementary angles. I can explain
this using a picture of a right triangle.
 I can use the angle measures to estimate side lengths.
 I can use side lengths to estimate angle measures.
Lesson 5-2: Applications of Right Triangle Trigonometry
 I can solve right triangles by finding the measures of all sides and angles in the triangles.
 I can use sine, cosine, tangent, and their inverses to solve for the unknown side lengths and angle
measures of a right triangle.
 I can draw right triangles that describe real world problems and label the sides and angles with
their given measures.
 I can solve application problems involving right triangles, including angle of elevation and
depression, navigation and surveying.
