It will have interior angles of 45, 45 and 90 degrees.
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
A cone does not have right angles.
A triangle is composed of 180 degrees. Two right angles = 180 degrees, the total number for all angles in a triangle. Thus a triangle can not have more than one right angle. l____________l <------ This is what two right angles look like, as you can see it cannot ever be a triangle.
It is a straight line that intersects another straight line at right angles or 90 degrees.
