If AB and CD bisect each other at point E, what is the length of AC? Type your answer into the text box, and then click Continue.
AB ? CD
AB = 6 CD = 8
AC = 5
Countinue
Since AB and CD are perpendicular, the angles around point E are all right angles. This means that we can draw a right triangle with legs of AE and CE, and a hypotenuse of AC.
Since AB and CD bisect each other, , and .
We can now plug the leg lengths into our Pythagorean theorem to find that:
