Describe, in your own words, the identity sin^2(x) + cos^2(x) = 1.
Crank

Look at the attached figure. We define the unit circle as a circle with center A in the origin (0,0) and radius 1.

Then, we consider a point P on the circumference. We call \alpha the angle between the positive half of the x axis and the radius AP.

We define

\cos(\alpha) = \overline{AD},\quad \sin(\alpha) = \overline{AC}

As you can see, ACD is a right triangle, and so we have

\overline{AD}^2+\overline{AC}^2=\overline{AP}^2

But since we know that AD is the cosine, AC is the sine, and AP is the radius (which is 1, and remains 1 when squared), we have just found out that

\cos(\alpha)^2+\sin(\alpha)^2=1

Answer:

Triangle PQR is similar to triangle STU because dilation (x,y) to (0.25x,0.25y) maps triangle PQR to triangle STU.
