Answer:
Q 14) (0,5) & (5,0) are not same.
(0,5) will lie on y- axis, as abscissa is 0.
(5,0) will lie on x- acis as ordinate is 0.
Q15) ( there is a typing mistake in question)
(the points should be like this
A (-1,0) ; B(0,1) ; C(1,0) ; D(0,-1) )
The figure is square in shape.
Since , diagonals of square are equal
BD= AC
AC= 2 units
angle ABC=90° ( angle of square)
by pythagoras theorem
AC²= AB²+BC²
AB= BC (sides of square)
AC²=AB²+AB²
AC²=2AB²
(2)²=2AB²
AB²=2
AB=√2 units
sides of square
AB = BC = CD = AD = √2 units
