If a radius of a circle is perpendicular to a chord then?
Then the radius bisects the chord.
If a radius of a circle intersects a chord it is perpendicular to that chord?
False
How is an apothem different from a radius?
An apothem is a line drawn perpendicular to a side of a regular polygon from the center of the polygon. A polygon is not a circle so it cannot have a radius. The radius of a circle is drawn from the center to any point in the circumference of the circle. You can draw a circle which encloses the regular polygon touching all vertices. The polygon is said to be inscribed in the circle. The apothem will be less than the radius because the radius is not perpendicular to any side, it can be drawn to a vertex but the apothem is perpendicular to a side, so it is shorter. Ex: draw a square with a circle which inscribes it. You can see that the apothem will be less than the radius.
What does perpendicular mean mathematicalywhat is radius?
Perpindicular lines are like the lines in the letter "T". The intersect each other at a 90 degree angle. A radius is the distance from the center of the circle to the circle itself. It is half the circle's diameter.
A line touching an arc or circle at only one point perpendicular to the arc's radius is said to be?
tangent
What is the perpendicular radius of a circle?
There is no such thing as a perpendicular radius.
If a radius of a circle is perpendicular to a chord then?
Then the radius bisects the chord.
What is a line perpendicular to a radius of a circle called?
A Chord. Or another radius!
If a radius of a circle is perpendicular to a chord at what point does it intersect the chord?
The radius of the circle that is perpendicular to a chord intersects the chord at its midpoint, so it is said to bisect the chord.
If a radius of a circle is perpendicular to a chord then it that chord?
Bisects
If a radius of a circle bisects a chord then it is to that chord?
Perpendicular.
What is line perpendicular to radius of circle called?
A tangent.
What does the radius-tangent theorem state?
Oh, dude, the radius-tangent theorem is like when a radius of a circle is perpendicular to a tangent line at the point of tangency. So, basically, it's saying that the radius and tangent line are gonna be like besties at that point on the circle. It's just a fancy way of saying they're gonna be all perpendicular and stuff.
What happens where a radius meets the tangent?
The radius and the tangent are perpendicular at the point on the circle where they meet.
A radius of a circle is perpendicular to a chord if and only if?
Bisects that chord
If a radius of a circle intersects a chord it is perpendicular to that chord?
False
If a radius of a circle intersects a chord then it bisects that chord?
If radius of a circle intersects a chord then it bisects the chord only if radius is perpendicular to the chord.
