Is it true or false that a radius is a chord of a circle?
False
Is the area of a circle twice the radius True or false?
True
Only one circle can be circumscribed about a given triangle true or false?
True.
Is it false The circumference of a circle is the distance around the circle?
It is true. The circumference of a circle is the distance around the circle.
True or false thee point which a tangent line meets a circle is called point of tangency?
True
Every circle is also an ellipse true or false?
True
True or false The foci of an ellipse can be outside the ellipse?
False
Is it true or false that the shape of the orbit of each planet is an eclipse?
False. The shape of the orbit of each planet is an ellipse, not an eclipse. An eclipse is the blocking of light, while an ellipse is a geometric shape that is elongated and not a perfect circle.
What are the properties that determines the true shape of ellipse?
Essentially an ellipse is a circle rotated about an axis without changing the point of view.
What shape of the planets orbit?
The planets orbit in an ellipse. An ellipse is described as a geometric shape where the sum of the distance from the foci at any point is the same. An ellipse has three main points. Two foci and a center like a circle. While a true circle has all its external points equidistant from its center, an ellipse measures its points from the foci, which are equidistant to the center point at on both sides. The planets ellipse is closer to a circle than an all out ellipse, however, the orbit is still a true ellipse. It is also true that the shape of a planet's orbit (an ellipse) is a conic section, i.e. the intersection of a right circular cone where the intersecting plane is not perpendicular to the cone's axis, but less than being parallel to one of the cone's nappes.
True or False A secant is a line or segment that passes through a point on the circle and the center of the circle?
False
Is it true or false that a radius is a chord of a circle?
False
A circle is named by its center true or false?
True.
An angle whose vertex is at the center of a circle is a middle angle of that circle True or false?
False. There are infinitely many angles at the centre of the circle.
True or False The circumcenter of a triangle is the center of the only circle that can be circumscribed about it.?
true!
Is each point that lies on a circle satisfies the equation of the circle true or false?
True
Is a circle always based on percentages true or false?
False.
