Answer:
Explanation:
all the lengths are the same:
ST = √(-1-2)²+(2-7)² = √9+25 = √34 = 5.831
TU = √(4--1)²+(-1-2)² = √25+9 = √34 = 5.831
UV = √(7-4)²+(4--1)² = √9+25 = √34 = 5.831
VS = √(2-7)²+(4-7)² = √25+9 = √34 = 5.831
The shape is a square (rectangle with equal sides) parallelogram (you could also call it a rhombus)
