State if the two triangles are congruent. If they are, state how you know.

Provide an example of a trigonometric function and describe how it is transformed from the standard trigonometric function f(x) = sin x, f(x) = cos x, or f(x) tan x using key features.

What is the missing step in this proof ?

The product of sin 30 degrees and sin 60 degrees is same as the product of
