iv) Use of distance formula to show that four non-collinear points from a
a) square
b) Rectangle
c) Parallelogram

Select a question from the list bellow to see the video of that Question directly (works best in Google Chrome Browser):
1.	Show whether the points with vertices (5, -2), (5, 4) and (-4, 1) are vertices of an equilateral triangle or an isosceles triangle?
2.	Show whether or not the points with vertices (-1, 1), (5, 4), (2, -2), (-4, 1) form a square?
3.	Show whether or not the points with coordinates (1, 3), (4, 2) and (-2, 6) are vertices of a right 	triangle?
4.	Use the distance formula to prove whether or not points (1, 1), (-2, -8) and (4, 10) lie on a straight line?
5.	Find k, given that the point (2, k) is equidistant from (3, 7) and (9,1).
6.	Use distance formula to verify that the points A(0, 7), B(3, -5), C(-2, 15) are collinear.
7.	Verify whether or not the points O(0, 0), A(sqrt(3), 1), B (sqrt(3), -1) are the vertices of an equilateral 	triangle.
8.	Show that the points A(-6, -5), B(5, -5), C(5, -8) and D(-6, -8) are vertices of a rectangle. Find the lengths of its diagonals. Are they equal?
9.	Show that the points M(-1, 4), N(-5, 3), P(1, -3) and Q(5, -2) are the vertices of a parallelogram.
10.	Find the length of the diameter of the circle having centre at C(-3, 6) and passing through P(1, 3).
