Enduring Understandings
Special right triangles have specific proportional relationships.
Trigonometric ratios are ratios of the relationship between the sides of a right triangle and its angles.
The sine and cosine of the complementary angles of a triangle are congruent.

Essential Questions
How does the measure of one acute angle relate to the ratio of two side measures in any right triangle?
How do trigonometric ratios relate to similar right triangles?
How are missing side lengths and angle measures found in a right or oblique triangle?
What strategies can be used to find missing parts of triangles and how can they be used to apply to real world problems?
Can trigonometry be used to find the area of a triangle?
