2. Move the pointer to one side of the triangle and press Í to
construct its perpendicular bisector.
Tip When the pointer is close enough to the triangle’s side, it
changes to a solid arrow and the side of the triangle blinks,
indicating that you can now press Í to construct the
perpendicular bisector.
3. Move the pointer close to another side of the triangle and
press Í to construct another perpendicular bisector.
4. Finally, move pointer to the last side of the triangle and press
Í to construct the third perpendicular bisector. Now the
perpendicular bisectors share a common point that you will use
as the center of the circumscribed circle.
