Answer:
Isosceles.
Step-by-step explanation:
We are going to check it with the distance formula
d(R,T) =
=
= ![\sqrt[2]{1+16}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B1%2B16%7D)
=
.
d(T,S) =
=
= ![\sqrt[2]{16+1}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%2B1%7D)
=
.
d(S,R) =
=
= ![\sqrt[2]{25+9}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B25%2B9%7D)
=
.
Then, as the triangle has two sides with the same length, the triangle is isosceles.
right isosceles
