Yes, by using the Baudhāyana-Pythagoras Theorem. The distance AD is the hypotenuse of a right-angled triangle. AD = square root of (4 squared plus 3 squared), which equals 5 units.
In a reflection across an axis, the shape, size and the coordinate corresponding to that axis remain the same. However, the sign of the other coordinate and the orientation (right-to-left) change.
(i) The fourth foot is at (8, 7). (ii) It depends on light and space. (iii) Width is 2 units, length is 3 units. Height cannot be determined from a 2-D coordinate plane.
With D1 at (9, 0) and R1 at (11.5, 0), the width is 2.5 units (50 cm if 1 unit = 20 cm). This is quite narrow and would not easily accommodate a wheelchair.
