Determine if the statement is most likely true or false in spherical geometry. Provide short explanations for your answers.
A four-sided figure with three right angles must be a rectangle (Spherical Geometry)
I think this is true, since the top and the bottom / adjacent sides will have to be congruent. Thus, the angle of the fourth corner of the rectangle must be 90 degrees in order for it to match up with what defines a rectangle.
