Question

the point (2,-2);(8,4);(5,7);(-1,1)from a rectangle​

Answer 1

Step-by-step explanation:

opposite sides of rectangle are congruent

d (P, Q)=

\sqrt{(8 - 2) {}^{2} } + \sqrt{(4 + 2} ) {?}^{2}

(8−2)

2

+

(4+2

)?

2

=

\sqrt{36 + 36}

36+36

=

\sqrt{72}

72

=

\sqrt{8 \times 9}

8×9

=

3 \sqrt{8}3

8

similarly, d (Q, R), d (R, S)and d (P, S) will be

3 \sqrt{8}3

8

hence,PQRS forms a rectangle...
