The figure below shows a parallelogram ABCD with diagonals AC and BD.

If it is given that angle CAB is 35°, which statement will guarantee that the parallelogram is a rhombus with all sides equal?

Angle DAC is 55° and angle DBA is 45°.

Angle DAB is 70° and angle AGB is 90°.

Angle AGB is 70°.

Angle DBA is 35°.

Thank you!!

i'd say different...

anonymous · Answer

Wait!! i'm wrong. Angle DAB is 70° and angle AGB is 90°. The diagonals form 90 degree angles when they intersect, and if cab is 35, then it is correct to say dab is 70 because the angles bisect. http://www.mathwarehouse.com/geometry/quadrilaterals/parallelograms/rhombus.php
