1.The vertices of triangle ABC have the following coordinates A(0,0) B(2,5),C(4,0). determine the lengths of the three sides of the triangle and what type of triangle is ABC.
------------------
The length of AC is obviously 4 units.

AB = sqrt%28diffy%5E2+%2B+diffx%5E2%29+=+sqrt%285%5E2+%2B+2%5E2%29+=+sqrt%2829%29
-----
BC = sqrt%28diffy%5E2+%2B+diffx%5E2%29+=+sqrt%285%5E2+%2B+2%5E2%29+=+sqrt%2829%29
