What are the coordinates of the circumcenter of a triangle with vertices A(0,1), B(2, 1) , and C(2, 5) ?

KatRina [158]

The circumcenter is where the perpendicular bisectors meet.
if you sketch the triangle, you will see that it is a right triangle, with the right angle vertex at (2,1)
one perpendicular bisector is x=1, another perpendicular bisector is y=3
they meet at (1,3)
so (1,3) is the answer.

If 50 percent of x=66 then x =

sasho [114]

Answer:

132

Step-by-step explanation:

50 % means half

so 66 is half of whatever x is.

to find x you have to multiply 66 by 2 or add 66 to 66 which will give you 132 either way.

What is the most precise term for quadrilateral ABCD with vertices A(3,1) , B(4,5) , C(7,5) , D(7,2) answer choices; A. KITE B.

SOVA2 [1]

Answer:

Step-by-step explanation:

Given are the vertices of a quadrilateral.

WE have to find the name of the quadrilateral

WE have slope of AC = (5-1)/(7-3) = 1

and slope of BD = (2-5)/(7-4) = -1

Since m1m2 =-1 we get

the diagonals cut at right angles

This property is special property for square, rhombus and kite only.

Let us check if diagonals bisect each other

Mid point of AC = $(\frac{3+7}{2} ,\frac{1+5}{2} =(5,3)$

Mid point of BD = $(\frac{4+7}{2} ,\frac{2+5}{2} =\neq 5,3)$

Since diagonals do not bisect this is neither rhombus nor square.

Only possibility is kite
