A painful workaround i just figured out is to exit the sketch, go to construct > point at center of shere/circle/torus, create two work points based off the different arcs, and then measure the distance between those two work points. Then, draw a second straight line that’s parallel to the first line on the opposite side of the circle. A chord of length 16 cm is drawn in a circle of radius 10 cm.

14 responses to skill builder: I can drag the line off the center of the circle. The center of the circle separates the diameter into two equal segments called radii (plural for radius).
Draw a square (square has four equal sides and four right angles) inside the circle with the corners exactly on the circular line then draw a straight line from one corner of the square to its opposite corner do it also on the other two corners left, the center of the circle will be the intersection point of the two straight lines drawn from the four corners of the square. The equation of a circle can be written using its center and radius: By placing the 90° corner of an object on the circle, we can find a diameter.
The equation of a circle: If you were to put the point on one of the marks and then made your second set of marks then the “cut” would be near 90 degrees and less. Kevin miller on june 16th, 2015 at 9:09 am said:
