In parallelogram ABCD, AC=BD. Is ABCD a rectangle?
false
Dihedral angle
Yes, provided: 1. ABCD is a closed plane figure (ie a closed 2-dimensional shape) 2. A square is considered a special case of a rectangle.
56 (: When we say polygon abcd is similar to polygon afge, they already told you which are the lines that are similar. ab:af=bc:fg=cd:ge etc. Lines ad and af are not similar in length and therefore cannot be used to find perimeter of polygon abcd even though the perimeter of polygon afge is given.

Yes, it is.
"abcd is not a parallelogram or it does not have any right angles." ~(P and Q) = ~P or ~Q
It is 16 units.
The answer will depend on what x is!
