1.
Using distance formula, determine whether the three points are collinear:
A(-2, 7), B(0, 4), C(2, 1)
2.
Using the distance formula, determine whether the three points D(1, -1), E(-2, 6)
and F(3, 4) are the vertices of a right triangle. Graph the triangle.
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
3.
Using the distance formula, determine whether the four points A(-2, 4), B(2, 0),
C(2, 8) and D(6, 4) are vertices of a square. Graph the square.

4.
Using the distance formula, find the unknown quantity. A(2, y), B(-2, -1);
distance AB = 5.
5.
Find the point P such that AP AB  r . A = (2, 4), B = (-5, 2), r = 2 5
6.
If P = (4, 7), B = (2, -1) and AP AB  2 5 , find A.
