Observe the big triangle : hypotenuse = 5 and adjacent side = 4.

\

Now find the opposite side by using Pythagorean theorem.

\

Pythagorean theorem : $\"\"$ .

\

Substitute hypotenuse = 5 and adjacent side = 4.

The given two triangles are similar, and corresponding sides are proportional.

\

So, they have the same function values.
