option c. square
step-by-step explanation:
points to remember
distance formula
length of a line segment with end points (x1, y1) and (x2, y2) is given by,
distance = √[(x2 - x1)² + (y2 - y1)²]
to find the sides of quadrilateral lmno
l (1, 1), m (4, 4), n (7, 1), and o (4, −2)
lm = √[(4 - 1)² + (4 - 1)²]
= √[3² + 3²]
= √(9+ 9) = √18
mn = √[(7 - 4)² + (1 - 4)²]
= √[3² + (-3²)]
= √(9+ 9) = √18
on = √[(4 - 7)² + (-2 - 1)²]
= √[(-3)² + (-3²)]
= √(9+ 9) = √18
lo = √[(4 - 1)² + (-2 - 1)²]
= √[3² + (-3²)]
= √(9+ 9) = √18
to find the type of quadrilateral
here lm = mn = no = lo = √18
all sides are equal.
therefore the correct answer is option c. square
