Answer:
Step-by-step explanation:
For PS
PS=√(x2-x1)²+(y2-y1)²
PS=√(-1+2)²+(1-4)²
PS=√1+9
PS=√10 units
For QR
QR=√(x2-x1)²+(y2-y1)²
QR=√(4-3)²+(5-2)²
QR=√10 units
For PQ
PQ=√(x2-x1)²+(y2-y1)²
PQ=√(3+2)²+(5-4)²
PQ=√26 units
For SR
SR=√(x2-x1)²+(y2-y1)²
SR=√(4+1)²+(2-1)²
SR=√26 units
→Here the given vertices are of a rectangle because its opposite sides are equal.
