Answer:

O is the center of the Circle

Step-by-step explanation:

Please see that , in order to draw a circumcircle we have to first draw the perpendicular bisectors of the sides. The point at which these perpendicular bisectors meet is called circumcenter and the it is the center of circumcircle passes through three vertices D, E and F.

This is because, When we draw the circle from these vertices, we can see that the three sides forms that three chords of the circle. And circle has a property that , the perpendicular bisectors of chords always passes through the center. And here o is the point through which all the perpendicular bisectors of all three chords are passing through. Hence 0 is the center

Look at the figure. Which step should be taken next to construct a line through point P perpendicular to BA?

alexira [117]

ANSWER:

C. Place the compass on point A. Open the compass to a point between point P and point B.

EXPLANATION:

A perpendicular is a line that would be at a right angle to line BA.

The next step is to chose a radius that is greater than PB or PA so as to construct the bisector. And this can be done by placing the compass on point A, and open the compass to a point between point P and point B.

Use this radius to draw an arc above and below the line, and repeat the same using B as the center with the same radius. This would form two intersecting arcs above and below line BA. Join the point of intersection of the arcs by a straight line through P. This is the bisector of line BA through point P.

The coordinates of the community center are (5, −1). Who has a house in the same quadrant as the community center?

WINSTONCH [101]

(5,-1) is located in quadrant IV......quadrant IV has (+ x, -y).....so any points that have (+ x, - y) are in this quadrant.
Example : (6,-3) is in this quadrant......(2,-4) is also in this quadrant.
So whoever has the house with (+ x, -y) is going to be in the same quadrant as the community center.
