Construct |

To place at a given point (as an extremity) a straight line equal to a given straight line.

• Start with the point A and line segment BC.

• Connect point A to point B.

• Construct the equilateral triangle DAB on line AB (see Proposition 1).

• Extend line DA to create line AE, and extend line DB to create line BF.

• Create the circle CGH around point B with a radius of BC.

• Create the circle GKL around point D with a radius of DG.

The line AL has been created equal to the given straight line BC from point A.

• Start with the point A and line segment BC.

• Connect point A to point B.

• Construct the equilateral triangle DAB on line AB (see Proposition 1).

• Extend line DA to create line AE, and extend line DB to create line BF.

• Create the circle CGH around point B with a radius of BC.

• Create the circle GKL around point D with a radius of DG.

The line AL has been created equal to the given straight line BC from point A.
