Algebra II Honors Agenda Q4 Week 1
Topic 7 A: Trigonometric Ratios and Acute Angles
Essential Question: How can ratios of lengths of sides within the right triangles help determine other lengths and angle measures in the triangles?
Vocabulary: co-function, co-function identities, co-secant, cosine, code tangent, reciprocal trigonometric functions, secant, sine, tangent
Find the missing side links of a 45-45-90 triangle.
Find the missing side links of a 30-60-90 triangle.

Essential Question: How can we extend the trigonometric ratios to angle greater than 90°?
Vocabulary: coterminal angles, initial side, reference angle, reference triangle, standard position, terminal side, unit Circle
Find the measures of an angle in standard position and its reference angle.
Work with angles in standard position.
Find coordinates of points on the unit circle

Use radian measure for angles.
Convert between degrees and radians.
Find the length of an arc of a circle.
Memorize the Unit Circle Packet - this has two parts (1) The craft project (first three pages put together or the project I did on the video with the oatmeal container) (2) the last page which is the completed unit circle.
