What are the different types of circles?
Types of Circles
- Concentric Circles. When two or more circles have the common centre, then these circles are called concentric circles. In the above figure, there are three circles inside one other.
- Contact of Circles. When outer surface of two circles are touching, it is known as contact of circles.
- Orthogonal Circles.
What is circle theory?
The perpendicular from the centre of a circle to a chord will always bisect the chord (split it into two equal lengths). Angles Subtended on the Same Arc. Angles formed from two points on the circumference are equal to other angles, in the same arc, formed from those two points.
What is the difference around a circle?
The distance around the boundary of a circle is called the circumference. The distance across a circle through the centre is called the diameter. The distance from the centre of a circle to any point on the boundary is called the radius. The length between two points around the circumference of a circle is an arc.
What is circle BYJU’s?
A circle is also termed as the locus of the points drawn at an equidistant from the centre. The distance from the centre of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.
How many diameter can a circle have?
Thus the diameter of the circle is twice as long as the radius. So, infinitely many diameters can be formed in the circle.
What do you call a two or more circles that have the same center but different radii?
Concentric Circles: Two or more circles that have the same center, but different radii.
What is Triangle BYJU’s?
In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
