# Triangle calculator

Calculator solve triangle given by three of its properties. Usually by three sides (SSS) or side-angle-side or angle-side-angle. Triangle enter like this:

a=3 b=4 c=5 ... triangle calc by three sides a,b,c.

B=45 c=10 a=9 ... triangle calc by two sides a,c and included angle B.

A=25 C=80 b=22

A=35 C=26 a=10

a=3 C=90 c=5 ... how to enter right angled triangle.

a=3 β=25 γ=45 ... triangle calc if we know the side and two angles.

a=3 β=25 T=12 ... triangle calc if know side, angle and area of triangle.

T=2.5 c=2 b=4 ... find side a if know sides b,c and area of triangle T.

ma=1 b=2.5 c=2 ... calculation of the triangle if we know one median and any two sides.

ma=1 mb=2.5 mc=2 ... triangle calc by three medians.

ha=220, hb=165 hc=132 ... triangle calc by three heights.

a=7 β=40 mc=5 ... triangle calc by one side, one angle and one median.

a:b:c=2:3:4 T=2.5 ... triangle where the known side ratio, and its area.

A:B:C=1:4:5 a=2 ... calculating triangle if known ratio of the internal angles and one side.

B=45 c=10 a=9 ... triangle calc by two sides a,c and included angle B.

A=25 C=80 b=22

A=35 C=26 a=10

a=3 C=90 c=5 ... how to enter right angled triangle.

a=3 β=25 γ=45 ... triangle calc if we know the side and two angles.

a=3 β=25 T=12 ... triangle calc if know side, angle and area of triangle.

T=2.5 c=2 b=4 ... find side a if know sides b,c and area of triangle T.

ma=1 b=2.5 c=2 ... calculation of the triangle if we know one median and any two sides.

ma=1 mb=2.5 mc=2 ... triangle calc by three medians.

ha=220, hb=165 hc=132 ... triangle calc by three heights.

a=7 β=40 mc=5 ... triangle calc by one side, one angle and one median.

a:b:c=2:3:4 T=2.5 ... triangle where the known side ratio, and its area.

A:B:C=1:4:5 a=2 ... calculating triangle if known ratio of the internal angles and one side.

What do the symbols mean?

a, b, c ... sides

A, B, C or α, β, γ ... angles

ha, hb, hc ... heights

ma, mb, mc ... medians

T ... area

p ... perimeter

s ... semiperimeter
