Complete the coordinate proof.

Given Coordinates of vertices of △OBC and △ODC
Prove △OBC and △ODC are isosceles triangles.
By the Distance Formula, OB =
, BC =
, OD =
, and DC =
. So △OBC and △ODC are isosceles by definition.

Mr and mrs smith buy tickets for themselves and their four children. the cost of an adult ticket is ? 6 more than the adult ticket. the total cost of the six tickets is ? 40.50 work out the cost of an adult ticket. in your working let c be the cost of the child ticket and a be the cost of the adult ticket.
