Circles: Exploring the Beauty and Significance of Circular Shapes Class Lectures

The STEM concept of input and output in circles geometry refers to the relationship between the measurements of a circle and the resulting calculations. The input in this case is the radius or diameter of the circle, which can be used to calculate the circumference, area, and other properties of the circle. The output is the resulting value of these calculations, which can be used to solve problems in a variety of fields, including engineering, physics, and mathematics. Understanding the input-output relationship in circles geometry is essential for solving complex problems and developing new technologies that rely on circular shapes and measurements. Overall, the STEM concept of input and output in circles geometry is a fundamental principle that underpins many important applications in science and engineering.

(A few) Circle Theorems

In mathematics, a theorem is a statement that has been proven on the basis of previously established statements, such as other theorems, and generally accepted statements, such as axioms. A theorem is a logical consequence of the axioms. The proof of a mathematical theorem is a logical argument for the theorem statement given in accord with the rules of a deductive system. The proof of a theorem is interpreted as justification of the truth of the theorem statement.

Angles and Cirlce Theorems with chords and tangents

In mathematics, the tangent function is a function that describes a line tangent to a curve. The concept of a tangent is used in analytic geometry, calculus, and trigonometry. The concept of a tangent is defined in every dimension, and a line that is tangent to a curve in the plane or in space is called a tangent line.

Arc Length

In mathematics, the length of an arc of a curve at a particular point is the measure of the segment of the curve joining the endpoints of the arc. The length of the curve between two points is the length of the shortest curve between them. The length of an arc of a curve at a particular point is the measure of the segment of the curve joining the endpoints of the arc.

Arc Length Examples

In mathematics, the length of an arc of a curve (or of a curve) is the measure of the curve (or curve) between two adjacent points on the curve.

Area of Sector

In trigonometry, the area of a sector of a circle is the segment of the circle. Its area is equal to half of the product of the radius and its arc length.

Central and Inscribed Angle Practice

In geometry, the angle of a polygon is formed by two adjacent sides of the polygon. Angles are usually assumed to be in a Euclidean plane with the circle taken for standard with a positive origin, or with the x-axis taken as positive. The measure of an exterior angle of a simple (non-self-intersecting) polygon is less than the sum of the measures of its interior angles. A convex polygon has all interior angles less than 180 degrees. An n-sided convex polygon has (n-2) interior angles less than 180 degrees.

Circle in Coordinates

A circle is the set of points in a plane that are equidistant from a given point, the centre, and lie on a given straight line, the radius. The distance between any of the points and the centre is called the radius. The point together with the radius is called the centre. The centre and the radius together are called the circumradius. Circles are the only sets in the Euclidean plane that are not closed.

Circles Intro and Terminology

In geometry, a circle is a simple shape of two-dimensional Euclidean space that is the set of all points in a plane that are at a given distance from a given point, the centre.

Circles and Coordinates Examples

In mathematics, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of a point or other geometric element on a manifold such as Euclidean space.

Circles and Tangents

In geometry, a tangent line to a circle is a line that just touches the circle at one point. If the circle has center (h, k) and radius r, the equation of a tangent line is

Circles and Tangents Examples

In mathematics, a tangent line to a plane curve at a given point is a straight line that "just touches" the curve at that point. More precisely, a tangent line is a line that has the same direction as the curve at the point where it touches the curve, and has a point of contact with the curve at that same point.

Inside and Outside Angle Theorem Practice

An angle is formed by two rays sharing a common endpoint, called the vertex of the angle. A ray is a line segment that starts at a point and extends indefinitely in one direction. A segment is a part of a line between two points. Angles formed by two intersecting lines are called intersecting angles. Angles formed by two intersecting lines that are not parallel are called complementary angles. Angles formed by two intersecting lines, one of which is a chord of the circle, are called inscribed angles. Angles formed by two intersecting lines, one of which is a chord of the circle, and the other a tangent to the circle, are called central angles.

Naming Circles Radii and Diameters

In geometry, the circle is a simple shape, the boundary of a region in the plane bounded by a circle of some radius centered at a fixed point called the center. The circle may be the boundary of a disk, and is then called a disk. A circle is a special kind of ellipse, the only kind of conic section, a plane curve resulting from the intersection of a cone by a plane parallel to an axis of the cone. A circle is a simple closed curve which divides the plane into two regions, an interior and an exterior. The boundary of the exterior region is called the circumference. The interior region is called the interior.

In mathematics, a trigonometric identity is an equality holding for all values of the trigonometric functions, usually expressed as a product of trigonometric functions. Trigonometric identities are often used to prove other identities. The most basic trigonometric identities are the Pythagorean identities, which involve the product of sine and cosine functions. There are also the addition formulas, which involve the sum of sine and cosine functions.
