shape has 4 side: at least one angle measure90 is it a.righ triangle .b.right trapezod c.right triangle b.rhombus

If it has four sides, it cannot be any form of triangle.
If at least one angle measures 90degrees, then it could be a right trapezoid, or a rhombus, or it could be neither.
There is not enough information to choose any of the four choices. Check the question please. 
Please proofread your choices and repost  along with your answer.
