Enter Side (a)

Given an equilateral triangle with side (a) equal to 17

Calculate the other relevant items in this triangle

Calculate Perimeter:

P = 3a

P = 3 x 17

P = 51

Calculate Semiperimeter s:

s =	P
	2

s =	51
	2

s = 25.5

Calculate Area (A):

A =	a2√3
	4

A =	172√3
	4

A =	289√3
	4

A =	500.56268338741

A = 125.14067084685

Calculate Bisector

ha-ma-ta =	a√3
	2

ha-ma-ta =	29.444863728671
	2

ha-ma-ta = 14.722431864335

Calc. Circumscribed Circle Radius

R =	a√3
	3

R =	29.444863728671
