Which chord is equal to two radii of a circle?
In order to answer this question, you need to know the definitions of the diameter, chord of a circle. A segment of a straight line connecting two points of a circle and passing through the center is called its diameter. A chord is a line segment that connects any two points of the circle. A chord (or rather the length of a chord) is equal to two radii (more precisely, the length of two radii) if and only if it passes through the center of the circle (otherwise the length of a chord will be less than the sum of the lengths of two radii, and the length of any chord cannot be greater than the sum of the lengths of two radii) ... This means that only the diameter of the circle (also a chord passing through the center of the circle) will satisfy this condition. Answer: the diameter of the circle. The word "diameter" comes from the Greek word "diametros" - transverse. Usually, the diameter is denoted by the Latin letter D. And, knowing the diameter (more precisely, its length), you can find the circumference by multiplying the diameter by a constant number P (pi), equal to about 3,14.
If I'm not confusing anything, a chord is a line segment connecting two points of a circle. Right? The double radius is the diameter. The largest possible chord passes through the center of the circle. What about what else can you say? Perhaps nothing.
The correct answer is the word DIAMETER. It is the diameter that is equal to two radii. The diameter connects the center of the circle and any other point on it. So don't be confused by this question anymore, you know the answer.
The question is very simple, if you remember the correct name from the geometry lessons. A chord is a line between two points on a circle. The two radii are the diameter. The correct answer is here - DIAMETER. This is the answer in this assignment.
