P = 6 s = 3 A = 2
What is the Answer?
P = 6 s = 3 A = 2
How does the Equilateral Triangle Calculator work?
Given a side (a), this calculates the following items of the equilateral triangle:
* Perimeter (P)
* Semi-Perimeter (s)
* Area (A)
* altitudes (ha,hb,hc)
* medians (ma,mb,mc)
* angle bisectors (ta,tb,tc)
* Circumscribed Circle Radius (R)
* Inscribed Circle Radius (r) This calculator has 1 input.
