Rectangle.
It could be:quadrilateral ortrapeziumtrapezoidisosceles trapezoid
parallelegram is the name it is a rectangle that is sort of slanted
No, a trapezoid could not have three right angles. If it did, it would be a rectangle, as the fourth angle would need to be 90 degrees as well. A rectangle is not a trapezoid.
They could be, but to form a trapezoid, They doesn't have to be. The legs of the trapezoid can be any length, so long as the the bases are parallel to one another.

No
No because a trapezoid has 4 sides and a triangle has three if a trapezoid had three then it would be a triangle. If you had 3 trapezoids you could make a triangle!
Three triangles could make a trapezoid that looks like this. ---------------- ( ) ( ) ( ) --------------------------

Not for all trap. Only for an isosceles trapezoid. Well, for an Isosceles trapezoid, it could be any of the two diagonals! In order to have an isosceles trapezoid with the diagonals equal, the isosceles part MUST be precise and specific.
what does a parallegram look like? what does a parallegram look like? what does a parallegram look like?
Not necessarily. The two sides of equal length could be adjacent sides.
