Question 33467
The vertices are at A(7,-4); B(-1,2); C(5,-6);
Length AB = Distance between (7,-4) and (-1,2) = Sqrt(64+36) = 10;
Length BC = Distance between (-1,2) and (5,-6) = Sqrt(64+36) = 10;
Length CA = Distance between (7,-4) and (5,-6) = Sqrt(4+4) = 2 sqrt(2);
Answer: The traingle has two equal sides.
