A quadrilateral is a kite if the diagonals are:
i) perpendicular
ii) bisect each other
iii) not equal ( together with conditions i and ii this would make the quadrilateral a square)
Another definition of the kite is :
a quadrilateral with 2 pairs of equal adjacent sides.
Let's check the choices one by one:
A. <span>∠M is a right angle and MK bisects ∠LMJ.
according to these, ML and MJ may well be not equal...
</span><span>B. LM = JM = 3 and JK = LK = √17.
</span>
this makes the quadrilateral a kite.
<span>C. MK intersects LJ at its midpoint
</span>
if they are not perpendicular, the quadrilateral is not a kite.
<span>D. The slope of MK is –1 and the slope of LJ is 1.
this only means that MK and LJ are perpendicular, but not whether they bisect each other,
Answer: only B</span>
Answer:
9.9 in
Step-by-step explanation:
x² = 7² + 7² = 98
x = 9.9
For any given regular polygon:
Apothem is a line segment from the center to the midpoint of one of its sides. Equivalenty, it is the line drawn from the center of the polygon that is perpendicular to one of its sides. Thus in our case, the apothem is OP. This is because OP is perpendicular to AB.
Radius is the distance from the center to any vertex. It is always the same for any vertex. The radius is the radius of the polygon's circumference. It is also know as circumradius. In our case the radius is OB or OA.
Perimeter of the polygon is the total distance around the polygon. In this case it will be given by:
p=AB+BC+CD+DE+EF+FG+GH+HA
