Copy a Line Segment
The simplest construction is to copy a line segment.
Given line segment AB, copy it to the dotted line as shown in red.
1) Using the Compass tool
, set the radius to the length of line segment AB by clicking point A then point B.
2) Create a new circle with a radius the length of segment AB centered at point C by clicking point C.
3) Create a new point where circle C and the dotted line intersect by using the Intersect tool
and clicking the dotted line and then the circle.
4) Create a new segment by selecting the Segment tool
, then click point C, then click the new point you created.
5) Verify the two segments are congruent by using the Segment Measure tool
. Click point A then point B. Then click point C and the new point you created. These should be equal.
