In a quadrilateral ABCD, AB || DC and AD || BC. Find the perimeter of triangle COD if the diagonals of the quadrilateral interse
aalyn [17]
Draw a diagram as shown below.

The diagonals are equal in length. Because AB || DC and AD || BC, the quadrilateral is a square.

Because the diagonals bisect each other at O, therefore
DO = BO = 10.
Likewise,
AO = CO = 10

Because AB = 13, therefore DC = 13.
The perimeter of ΔCOD is CO + CD + DO = 10 + 13 + 10 = 33 in

Answer: 33 in

natka813 [3]

Answer:

650miles

Step-by-step explanation:

Using the Pythagorean theorem: a^{2} + b^{2}   = c^{2}

600^{2} +250^{2} = c^{2}

\sqrt{600^2 + 250^2}   = c

c =  650miles
