Find the area of an isosceles triangle if its hypotenuse is 2 cm.

Triangle ABC AC-hypotenuse AC = 2cm
By Comrade Pythagoras
AC ^ 2 = AB ^ 2 + BC ^ 2
Because The triangle is isosceles, then AB = BC let AB = x
2 ^ 2 = (2x) ^ 2
4 = 4x ^ 2
x ^ 2 = root of 1
x ^ 2 = – root of 1 (not a solution, since the length cannot be negative)
x = 1
S = 1 / 2ah
S = 1/2 * 1 * 1 = 0.5
Answer: 0.5
