With vertices of a parallelogram
1. a parallelogram has the vertices (0, 3), (3, 0), (0, -3) and (-3, 0). determine what type of parallelogram [10 points]. find the perimeter and area [10 points].

2. a parallelogram has the vertices (-1, 2), (4, 4), (2, -1) and (-3, -3). determine what type of parallelogram [10 points]. find the perimeter and area [20 points].

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
