Question 147115: A Triancle is Isosceles if it has at least two sides that are congruent. if the vertices of a triangle are given as A (0,8), R (-4,5), and T (-1,1) determine if Triangle ART is Isosceles or not.

A Triancle is Isosceles if it has at least two sides that are congruent. if the vertices of a triangle are given as A (0,8), R (-4,5), and T (-1,1) determine if Triangle ART is Isosceles or not.
AR+=+sqrt%284%5E2+%2B+3%5E2%29
AR = 5
-------
RT+=+sqrt%283%5E2+%2B+4%5E2%29
RT = 5
AB = RT, so it's isosceles.
