What is the radius of the circumscribed circle of △ ABC?
For a triangle △ABC, let s = 12 (a+b+ c). Then the radius R of its circumscribed circle is R=abc4√s(s−a)(s−b)(s−c). In addition to a circumscribed circle, every triangle has an inscribed circle, i.e. a circle to which the sides of the triangle are tangent, as in Figure 12.

How do you make a hexagon in a circle?
Explanation of method. As can be seen in Definition of a Hexagon, each side of a regular hexagon is equal to the distance from the center to any vertex. This construction simply sets the compass width to that radius, and then steps that length off around the circle to create the six vertices of the hexagon.

When constructing a new angle congruent to a given angle First you must?
First, mark a point that represents the new angle’s vertex and draw a line that extends outwards from this point. Place the compass at the original angle’s vertex and draw an arc that crosses through the two lines of this angle, then repeat this step to create an arc for the congruent angle.
Which of these is a correct step in constructing an angle bisector?

What is circumscribed and inscribed circle?
A circle is circumscribed about a polygon if the polygon’s vertices are on the circle. For triangles, the center of this circle is the circumcenter. A circle is inscribed a polygon if the sides of the polygon are tangential to the circle. For triangles, the center of this circle is the incenter.
How do you find the equation of a circle inscribed in a triangle?
Given A, B, and C as the sides of the triangle and A as the area, the formula for the radius of a circle circumscribing a triangle is r = ABC / 4A and for a circle inscribed in a triangle is r = A / S where S = (A + B + C) / 2.

How is constructing an angle bisector different to constructing a perpendicular bisector?
Constructing an angle bisector creates a line that bisects an angle, whereas constructing a perpendicular bisector creates a line that bisects a line segment. … A line can then be drawn through the two points where the arcs intersect to create a perpendicular bisector.

The simplest way to draw a hexagon in AutoCAD is to use the polygon tool, entering six as the number of sides. If you know the radius you’d like to use, then you can choose to size the polygon from the center. You can then choose if you want the hexagon inscribed within the radius, or circumscribed outside the radius.
