Answer:
A, C and D
Explanation:
6: since a rhombus is a type of parallelogram, we know that opposite angles will be equal so GDE will be 28 degrees as well.
7: The sides are perpendicular to each other so the gradient perpendicular to AB will be the negative reciprocal of 1/2 so -2.
8: Rhombuses have 4 equal sides but only 2 pairs of equal angles.
