In quadrilateral ABCD, AB and DC are parallel, AD and BC are parallel. Find the perimeter of triangle COD if point O is the intersection of diagonals and AC = 20, BD = 20, AB = 13. How do I solve this?
From the information given we can identify what type of quadrilateral we are given.
The opposite sides are given as parallel, so
Draw a diagram and fill in all the information to make it easier.
The diagonals of a rectangle bisect each other, they share the same midpoint,
The sides of
The lengths of all these sides known so we can find the perimeter:
