What is a triangle in a circle that is formed by two chords and a diameter?
If a triangle is drawn in a circle with a diameter as the base of the triangle, then the angle opposite that diameter is a right angle. This is an extension of the theorem that the angle which an arc of a circle subtends at the centre of a circle is twice the angle which the arc subtends at the circumference. In the case of a diameter, then the angle subtended at the centre is 180° and thus the angle at the circumference is 90°.
What is a chord of a circle?
A chord of a circle is a line segment drawn from any point on the curcumference of the circle to any other point on the circumference of the circle. The chord may pass through the center of the circle, in which case it is the diameter of the circle. The length of the chord will less than or equal to the diameter of the circle but greater than zero. If you draw a circle and start drawing chords, you'll quickly discover that there are an infinite number of unique chords that can be drawn in that circle. A link can be found below, and you can gather more information with the "click" of your mouse.
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 diagonals does a circle have?
If you are referring to the segment passing through the center of the circle and touching the circumference of the circle then it's the diameter of the circle.There can be infinite diameters drawn inside a circle.
What is a segment joining the center of a circle to a point on the circle?
That particular segment is the radius of the circle, which is half of the diameter.The radiusThe line segment (distance) from the center of a circle to any point on the diameter of the circle is called the radius.radius which is half the diameter and the area of the circle is pi*radius squared.A chord of a circle is a line segment that has its endpoints on the circumference of the circle.If a line segment is drawn from the center of the circle to the circumference (or curve), it is called a radius.If a chord passes through the center of the circle, its length is the diameter (width) of the circle.Radius joins the center of the circle to any point on the circle and a chord cuts through the circle but does not pass through the center.length of a line segment joining center andany poit on a circleThis is the definition of the radius of the circle, which is equal to one-half the diameter of the circleThe radius of the circle, equal to one-half of its diameter, is any line that goes from the center of the circle to any point on the circle.The distance between the center and the edge of a circle is called the radius.The distance between the center and edge of a circle is called the radius.RadiusThe distance from the center of a circle to its outer edge is the Radius.A line drawn between the center of a circle and the edge of the circle is called the radius.Radius.Diameter is the entire distance across the circle, and radius is from the center to the edge (so 2r=D).Radius :dRadiusThe distance is known as the radius and is drawn in a straight line from the centre of the circle to the edge of the circle itself
What is A line segment drawn through the center of the circle with endpoint on the circle?
A line segment drawn through the centre of a circle and having endpoints on the circumference of that circle is called the diameter. Notably, a line segement with one endpoint at the centre of the circle and one anywhere on the circumference of the circle is called the radius, and is exactly half the length of the diameter.
What is radius equals 12 inches?
Every circle has a point called the centre. A straight line drawn through the centre and extending both ways to intersect with the circle at opposite points is called the diameter. A straight line drawn from the centre to intersect with one point of the circle is called the radius. In this case, the length of that straight line is 12 inches.
If a circle has a diameter of 15 inches can it also have a chord of 20 inches and how?
No. A chord is a straight line drawn between any two points on the circumference of a circle. The longest chord is when the points are on opposite sides of the centre of the circle (and passes through the centre of the circle). The straight line which joins the points on opposite sides of the centre (through the centre) is called the diameter of the circle. Therefore the longest chord possible is the diameter of the circle. A circle with a diameter of 15 in can have a chord with a maximum length of 15 in.
A radius of a circle is 13 1 6 what is the diameter?
By definition the radius of a circle is a straight line drawn from the centre of a circle to its circumference. If you extend that line to the opposite side of the circle it becomes the diameter. The length of the diameter is twice the length of the radius. If the radius is 1316 the diameter is 2632
How do you find the length of a radius drawn from the center of the circle to a tangent?
It is the same length from the centre to any point on the circumference so just measure it
How do you find the center of a circle with the diameter of 5 meters?
The diameter of a circle is a straight line drawn from edge to edge passing through the centre. Therefore, the centre of the circle is half the diameter: 5/2=2.5 metres.
What is a triangle in a circle that is formed by two chords and a diameter?
If a triangle is drawn in a circle with a diameter as the base of the triangle, then the angle opposite that diameter is a right angle. This is an extension of the theorem that the angle which an arc of a circle subtends at the centre of a circle is twice the angle which the arc subtends at the circumference. In the case of a diameter, then the angle subtended at the centre is 180° and thus the angle at the circumference is 90°.
How many tangents can be drawn from a point on the circumference of a circle?
Only one which is a tangent to that circle.
Can there be a straight circle?
Circle in 2D is a straight figure drawn on a plane. But if we take it as a sphere,it cannot be straight.
How do you find the diameter?
The diameter of a circle is the length of a straight line drawn through the center of the circle to its edges.Or, measure the circumference of the circle and divide by pi (3.14159).Or you can multiply the radius times twoTo get diameter you have to find the radius and then double it to get the diameter
What is an example of a radius in math?
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
What is a chord of a circle?
A chord of a circle is a line segment drawn from any point on the curcumference of the circle to any other point on the circumference of the circle. The chord may pass through the center of the circle, in which case it is the diameter of the circle. The length of the chord will less than or equal to the diameter of the circle but greater than zero. If you draw a circle and start drawing chords, you'll quickly discover that there are an infinite number of unique chords that can be drawn in that circle.
