Answer:
B.) Orthogonal
Step-by-step explanation:
Two vectors u and v whose dot product is u·v=0 are said to be orthogonal
u = <6, -2>, v = <2, 6>
u·v = u1*v1 + u2*v2
6*2 + -2 * 6
=12 -12
=0

Answer:
EF = HG and EF || HG
Step-by-step explanation:
A quadrilateral is a polygon shape with four sides and four angles.
A parallelogram is a quadrilateral with two pairs of parallel sides. The following are properties of a parallelogram:
- Opposite sides are equal and parallel.
- Opposite angles are equal to each other.
- Consecutive angles are supplementary
- The diagonals of a parallelogram bisect each other.
If Quadrilateral EFGH with diagonals EG and HF is a parallelogram then EF = HG and EF || HG
