Provide a Two Column Coordinate Proof

1. Determine whether parallelogram JKLM with vertices J(-1, 1), K(4, 1), L(4, 6), and M(-1, 6) is a rhombus, square, rectangle, or all three. Provide a coordinate proof to justify your answer. 2. Provide a two-column proof. Given: Quadrilateral ABCD is a parallelogram Prove: Triangle ABC is congruent to Triangle CDA D B
