Question

WIL GIVE MEDAL! HELP
Quadrilateral ABCD has coordinates A (3, -5), B (5, -2), C (10, -4), D (8, -7). Quadrilateral ABCD is a (4 points)

Answer 1

rectangle, because opposite sides are congruent and adjacent sides are perpendicular
square, because all four sides are congruent and adjacent sides are perpendicular
parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular
rhombus, because all four sides are congruent and adjacent sides are not perpendicular

Answer 9

(1, 3.5)
(1.5, 4)
(2, 3.5)
(2, 4)

Answer 10

\[cordinate \ of \ point \ B \ are \ (0,6) \ and \ point \ D\ are\ (3,2)\\ now \ using\ distance\ formula\ btw \ B \ and \ D\\ BD=|\sqrt{(0-3)^2+(6-2)^2}|\\ \implies \ BD= |\sqrt{3^2+4^2}|\\BD=|\sqrt{9+16}|\\BD=|\sqrt{25}|\\BD=5\ unit\\ \let \ \mid \ points\ of \ BD \ be\ (x,y)\\ then\ x=\frac{ 0+3 }{ 2}= \frac{ 3 }{ 2 }=1.5\\ y= \frac{ (6+2) }{ 2}=\frac{ 8 }{ 2 }=4\\ \therefore\ midpoints\ of\ BD \ are \ (1.5\,\ 4)\ Q.E.D.\\\\ -----LOGICFALL\ Co.-----\]

Answer 11

oh! no, no need to find distance BD, mistakely done! Just see the last part. @seth23 ANS= (1.5, 4)
