# The diagonal of a square formed by the points (1, 0) (0, 1) (–1, 0) and (0, –1) isA. 2B. 4C. √2D. 8

Formula used: Let the points be A (1, 0), B (0, 1), C (–1, 0) and D (0, –1)

Distance of diagonal AC

AC = √ ((–1 – 1)2 + ( 0 – 0)2)

AC = √ ((–2)2 + (0)2)

AC =√ (4 + 0)

AC = √ 4

AC = 2

Option A is correct.
