What is a Chords in circles?
A chord is a straight line drawn through a circle which divides the circle into two parts. The line can be drawn anywhere in the circle EXCEPT the center where it becomes the diameter.
How many diameters of a circle can be drawn?
There are infinite diameters within a circle.
What circle is the largest circle that can be drawn around a sphere such as a globe?
general astronomy
Can a circle always be drawn around a four-sided shape?
If you mean can a circle always be drawn round a quadrilateral so that the quadrilateral is enclosed within the circle then yes as long as the diameter of the circle is large enough. If you mean can a circle always be drawn around a quadrilateral so that it passes through all vertices then only if the opposite angles of the quadrilateral add up to 180o - such quadrilaterals are called cyclic quadrilaterals.
There are 7 points on a circle how many line segments can be drawn joining the points?
Use the formula n(n-1)/2 --> 7(7-1)/2 = 7(6)/2 = 42/2 = 21.

A compass draws all points that are equidistant from a fixed point thereby creating a locus of points for a circle?
A circle is the locus of all points equidistant from a given point, which is the center of the circle, and a circle can be drawn with a compass. (The phrase "locus of points for a circle" does not seem to be conventionally defined.) or true
All the points on a plane that are equidistant from a single point?
All points on the circumference of a circle drawn on a plane are equidistant from the single point on the plane which is the center of the circle.
Which of the rectangle the square the circle and the parallelogram which doesn't fit?
The circle doesn't fit because it is a curve. The other figures are drawn with line segments; they're polygons. In fact, the other figures are all quadrilaterals.
What is the Name of the triangle formed by joining of points formed by the perpendiculars drawn from vertexes to the opposite side?
isosceles triangle
What is projection of line?
The line joining the feet of the perpendiculars drawn from all the points of the line onto a preselected plane.
