Right Triangles and Trigonometry
Enduring Understandings:
Essential Questions:
 Some attributes of geometric figures, such as length,
area, volume, and angle measure, are measurable.
Units are used to describe these attributes.

right triangle?
 How do trigonometric ratios relate to similar right
triangles?
