Hi!

I have a Geometry worksheet I need to get done for tomorrow. It's a really easy thing, I guess...but I'm a bit stuck.

The lengths of two sides of a triangle are 4yd and 8yd. Which of the following CANNOT be the length of the third side?

A. 3yd

B. 5yd

C. 8yd

D. 9yd

I forgot if the two sides of a triangle had to be greater than or less than the third side.

Thanks:d
