In triangle ABC, AB = 6 cm, BC = 8 cm, and AC = 10 cm. Lines PQ, PR, and QR are drawn parallel to sides AB, BC, and AC respectively, such that P, Q, and R lie on the sides of the triangle to form a parallelogram PARQ. The perimeter of the quadrilateral PARQ is:

If B is the center of a circle and lines AD and CD are tangent segments drawn from an external point D, then which of the following classifications apply to quadrilateral ABCD? (a) Kite (b) Cyclic quadrilateral (c) Rhombus (d) Trapezium
