The radius
it is called the "center"
To draw a regular decagon using a compass, start by drawing a circle with your compass. Next, mark a point on the circle to serve as one vertex of the decagon. Then, use the compass to construct the radius and divide the circle into ten equal segments by marking points at equal angles (36 degrees apart). Finally, connect these points with straight lines to form the decagon.
It is a marking gauge.
To construct a 25-degree bisection angle with a compass, start by drawing a straight line and marking a point ( A ) on it. Next, construct a 50-degree angle at point ( A ) by using a compass to draw an arc from ( A ) that intersects the line at point ( B ), then use the same arc to find point ( C ) such that ( \angle CAB = 50^\circ ). Finally, bisect ( \angle CAB ) by drawing an arc from points ( B ) and ( C ) that intersects at point ( D ), and draw a line from ( A ) through ( D ). This line creates the desired 25-degree angle with the original line.
To construct a 125-degree angle using a compass and ruler, start by drawing a straight line and marking a point on it (point A). Using the compass, draw an arc centered at point A that intersects the line. Without changing the compass width, place the compass point on one intersection and draw another arc above the line. Repeat this from the other intersection, creating two arcs that intersect. Finally, use a ruler to draw a line from point A through the intersection of the arcs, forming a 125-degree angle with the original line.
That's going to become the 'radius' of the circle you draw.
Well, honey, that distance is what we call the radius of the circle. It's the measurement from the center point (the pivot) to the outer edge (the marking point) where all the magic happens. So, grab that compass, find your center, and strut your stuff drawing those circles like a pro!

Clear and dimensional accuracy in marking out is critical in all circumstances. You spend the time marking something out then you or others should be able to see it clearly. Drawing requirements must be followed at all times you mark out to the tolerance the drawing states.
A drawing or marking that represents a feature on a map is called a symbol. These markings make up the map key.

oh
it is for marking and measuring a distance
It would be a hole punch.

To construct a 125-degree angle using a compass and ruler, start by drawing a straight line and marking a point on it (point A). Using the compass, draw an arc centered at point A that intersects the line. Without changing the compass width, place the compass point on one intersection and draw another arc above the line. Repeat this from the other intersection, creating two arcs that intersect. Finally, use a ruler to draw a line from point A through the intersection of the arcs, forming a 125-degree angle with the original line.
The middle thing on a compass is called the compass rose. It is the circular marking that shows the cardinal directions (north, south, east, west) and sometimes intermediate points on a map or compass.
