Question

three vertices of a rectangle have cordinates (0,0) (7,0) (7,3) Which are the coordinates if the missing vertex? A:(3,7) B:(3,3) C:(3,0) D:(0,7) E:(0,3)

Answer 1

The fourth vertice is E:(0,3)

E: (0,3)

To check:
Distance between (0,0) and (0,3) is the same that (7,0) and (7,3)
√[(0-0)²+(0-3)²]=√[(7-7)²+(0-3)²]
3=3

And we have the same distance between (0,0) and  (7,0) and the points (0,3) and (7,3)
√[(0-7)²+(0-0)²]=√[(0-7)²+(3-3)²]
7=7
