How to make conjectures with justifications about geometric ideas.
- The benchmark will be assessed using MC (Multiple Choice) items.
- Items may include proofs about congruent/similar triangles and parallel lines.
For his mathematics assignment, Armando must determine the conditions that will make quadrilateral ABCD, shown below, a parallelogram.
Given that the m∠ DAB = 40°, which of the following statements will guarantee that ABCD is a parallelogram?
- m∠ ADC + m∠ DCB + m∠ ABC + 40° = 360°.
- m∠ DCB = 40°; m∠ ABC = 140°
- m∠ ABC + 40° = 180°
- m∠ DCB = 40°
