Calculator For Isosceles

Triangle having two sides equal in length and also two angle are equal is mostly refered to Isosceles Triangle.Two Sides having equal measure and one side which is base is having different measureas compare to another sides. BY using Isosceles Triangle we will get 7 Unknown variables if we know the 3 variables value.

Select Which value you are providing (Side Length(a) , Side Length Base(b)) input value and Click on Calculate to get Side Length(c) Perimeter(P), SemiPerimeter(s), Area(K), Altitude of side a (ha), Altitude of side b (hb), Altitude of side c (hc).

Triangle having two sides equal in length and also two angle are equal is mostly refered to Isosceles Triangle.we can get the value of Side (a) , Side (b) , Side (c) , Area (K) , Perimeter (P) , SemiPerimeter (s) , Altitude of Side Length (ha) , Altitude of Base (hb) , Altitude of Hypotenuse (hc). Get the value of seven Unknown variables by passing the value of two known variables.By Using following formula :

Side Length :

a = c
Where
a = Side Length
c = Side Length

Angle :

A = C
Where
A = Angle
C = Angle

Altitude :

ha = hc
Where
ha = Altitude a
hc = Altitude c

Perimeter :

P = a + b + c
Where
a = Side Length
c = Side Length
b = Side Length

Semiperimeter:

s = (a + b + c) / 2
Where
a = Side Length
c = Side Length
b = Side Length

Area of Isosceles:

K = b/4 * (4a2-b2)
Where
a = Side Length
c = Side Length
b = Side Length

Altitude a of Isosceles Triangle :

ha = (b/2a) *(4a2-b2)
Where
a = Side Length
c = Side Length
b = Side Length

Altitude b of Isosceles Triangle :

hb = (1/2)*(4a2-b2)
Where
a = Side Length
c = Side Length
b = Side Length

Altitude c of Isosceles Triangle :

hc = (b/2a)*(4a2-b2)
Where
a = Side Length
c = Side Length
b = Side Length
