An excenter is a point at which the line bisecting one interior angle meets the bisectors of the two exterior angles on the opposite side. This is the center of a circle, called an excircle which is tangent to one side of the triangle and the extensions of the other two sides.

The incenter is the point of intersection of the three angle bisectors. The angle bisectors of a triangle are each one of the lines that divide an angle into two equal angles. The incenter is the center of the circle inscribed in the triangle.

An inscribed circle is the largest possible circle that can be drawn on the inside of a plane figure. For a polygon, each side of the polygon must be tangent to the circle. All triangles and regular polygons have circumscribed and inscribed circles.

In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is a triangle center called the triangle’s incenter. See also Tangent lines to circles.

Incenter of a triangle – formula A point where the internal angle bisectors of a triangle intersect is called the incenter of the triangle. If the coordinates of all the vertices of a triangle are given, then the coordinates of incircle are given by, (a+b+cax1+bx2+cx3,a+b+cay1+by2+cy3)

Properties. Every circle has an inscribed triangle with any three given angle measures (summing of course to 180°), and every triangle can be inscribed in some circle (which is called its circumscribed circle or circumcircle).

In AA, the equilateral triangle represents the three part answer – Unity, Recovery, and Service – to a three part disease – Physical, Mental, and Spiritual, while the circle represents AA as a whole.

Triangle tattoos can mean wisdom, love, and connection The combination of thought and emotion supposedly opens the mind up to higher wisdom, making the triangle a very sacred symbol. Couples and BFFs often share this tattoo by getting one half of the design each.

The shape of Egyptian pyramids is thought to represent the primordial mound from which the Egyptians believed the earth was created. The Egyptians believed the dark area of the night sky around which the stars appear to revolve was the physical gateway into the heavens.

The construction of the pyramids is not specifically mentioned in the Bible. What we believe about their purpose does not impinge on any biblical doctrine.

Amenemhet is Mighty

The Egyptian sun god Ra, considered the father of all pharaohs, was said to have sat upon a pyramid-shaped mound of earth which had emerged from the primordial sea. The pyramid’s shape is thought to have symbolized the sun’s rays.
