Draw four perpendicular lines that cross each other. Like this: # except at right angles. Count the angles - 4 in the centre square, and 12 around the overlapping parts.
4 perpendicular lines (Assume that it is perpendicular)----> # 2 lines intersected made 4 right angles. 4 lines make 16 right angles. 4*4=16

None normally unless its in the shape of a rectangle which has 4 perpendicular lines creating 4 right angles

No because they will form 4 right angles of 90 degrees

If you form the digits with a seven-segment LED display, then all of the digits except '1' have perpendicular lines.
