This diagram is a straightedge and compass construction.
Three congruent, intersecting circles, each pass through the others center at points A, B and C. Circles center A and C intersect at points H and B. Circles center A and B intersect at points D and C. Circles center B and C intersect at points F and A. Segment D H passes through A. Segment D F passes through B, Segment F H passes through C, Segments C D and A B intersect at point E.
This diagram is a straightedge and compass construction.
Line segment
Here are 2 points in the plane.
In this diagram, line segment
Two line segments that intersect. Line segment C D is the perpendicular bisector to line segement A B. Segments intersect at Point M, a right angle. Point E sits to the left of Points M and C, and above Point A.
The diagram was constructed with straightedge and compass tools. Name all segments that have the same length as segment
Starting with 2 marked points,
In the construction,
Two congruent circles, each pass through the others center at points A and B, and intersect at points D and E. Point C lies on circle A, and points A, B, C are collinear and equidistant. Radii DB and EB and chords CD and CE are drawn forming quadrilateral C D B E.
