Find the length of base of a triangle without using Pythagorean Theorem

I'm curious whether it is possible to find the length of base of the triangle without using Pythagorean Theorem

No Pythagorean Theorem mean:

=> No trigonometric because trigonometric is built on top of Pythagorean Theorem. etc $\mathrm{sin}\theta =\frac{a}{r}$

=> No Integration on line or curve because the integration is built on top of Pythagorean Theorem. etc: $s(x)=\int \sqrt{{f}^{\prime}(x{)}^{2}+1}$

In your own words, discuss how the diameter and circumference of all circles-small or large-are related. If a circle has diameter D centimeters and circumference C centimeters, then what is an equation that relates D and C? Explain in detail why your equations holds for all circles, no matter what size.
