Geo.4 Right Triangle Trigonometry

I can explain why knowing one acute angle in a right triangle determines the ratio of the side lengths.

I can determine the side lengths of triangles with 45, 45, and 90 degree angles.

I can determine the side lengths of triangles with 30, 60, and 90 degree angles.

I can build a table of ratios of side lengths of right triangles.

I can use a table of ratios of side lengths of right triangles to estimate unknown angle measures.
I can use a table of ratios of side lengths of right triangles to estimate unknown side lengths.

I can use cosine, sine, and tangent to find side lengths of right triangles.

I can use cosine, sine, and tangent to find the height of an object.

I can explain why $\sin(\theta)=\cos(90-\theta)$.

I can use arccosine, arcsine, and arctangent to find angle measures in right triangles.

I can use trigonometry to solve problems.

I can explain how to use regular polygons to approximate the value of $\pi$.
