If the radius of the circle is known, the diameter formula is diameter=2R, where R equals the circle's radius. If the circumference of the circle is known, the diameter is found using diameter=C/Pi, where C is the circumference and pi is approximately 3.142.
Know MoreIf the area of a circle is known, the diameter is the square root of 4A/Pi, where A is the area of the circle and Pi is approximately 3.142. The diameter of the circle is the length of the line through the center of the circle that touches two of the points on its edge The center of the circle is the midpoint of the diameter. A diameter may also be referred to as a chord, which is any line that joins two points on a circle. The diameter is the longest chord on any circle.
Learn MoreA geometric line is a one-dimensional object that extends in a straight direction for an infinite distance. Line segments are often used in drawing and mathematics, and they are a portion of a geometric line that spans from one defined point to another.
Full Answer >The segment addition postulate states that if a line segment has three points, then this line segment may be considered two line segments. An example is a line featuring points A, B and C with A and C being the endpoints. In this example, AC = AB + BC.
Full Answer >A closed plane figure with three line segments is called a triangle. If the closed plane figure has more than three line segments, it is called a polygon. The word “poly” means “many,” and there are different names for such figures.
Full Answer >The SSS theorem in geometry stands for side-side-side, and it is used to prove that two triangles are congruent. SSS states that if three corresponding sides of two triangles are congruent, then the triangles are congruent. If two triangles are congruent, all corresponding side lengths and angle measurements of the triangle are also the same.
