Suppose ABCD is a rectangle. Using the RHS theorem, prove that triangles ABC and ADC are congruent.
ABCD is a rectangle
AC is a diagonal
In Δ ABC and Δ ADC
AD = BC (Opposite sides of a rectangle)
∠ADC = ∠ABC = 900(Angle of a rectangle)
AC = AC (Common side)
So Δ ABC and Δ ADC is congruent by R.H.S. axiom of congruency.
