A rectangle that measure 4 by 6 has vertices A,B,C and D. The Midpoint (E) of CD is labeled, and ADE is drawn to form a 3-4-5 triangle. Then, it is reflected over the hypotenuse to get triangle AD'E. How far away is D' from C?

Your diagram is not drawn correctly!!!cheeky

 

CE = ED' = 3

 

Find angle CED'

 

Use the law of cosines to find the length of CD'

 

Warning:smiley if you do not even attempt to solve this, I'll delete my post. 

 

I know the answer, but I won't tell you.laugh
