Question

Draw a rectangle and one of its diagonals. Determine if the two triangles formed are congruent. If they are congruent, prove using a two-column, flow or paragraph proof that the diagonal divides the rectangle into two congruent triangles? If the two triangles are not congruent, explain why not using mathematical language.
