t_b = angle bisector of side b

m_a = median of side a

m_b = median of side b

h = height of the isosceles triangle

x = the equal angle of the isosceles triangle

y = third angle of the isosceles triangle

r_i = inscribed circle radius of the isosceles triangle

r_c = circumscribed circle radius of the isosceles circle
