The slope of EF is .

Which statements are true? Check all that apply.

EH is parallel to FG.
EF is perpendicular to EH.
HG is neither parallel nor perpendicular to FG.
Quadrilateral EFGH is a rectangle because it is a parallelogram with four right angles.
Quadrilateral EFGH is a trapezoid because it has exactly one pair of parallel opposite sides.

A quadrilateral in geometry is a four-sided polygon with four sides and four corners (vertices).
The Latin words Quadri, a variation of four, and latus, meaning "side," are the source of the name.
In reference to other polygons, it is also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon).
Since "gon" is an anagram for "angle," it is also known as a quadrangle or 4-angle.
Display style "square ABCD" is sometimes used to indicate a quadrilateral with the vertices A, B, C, and D.

Therefore, the correct option is (B) EF is perpendicular to EH.
