1.One way to construct an isosceles triangle is to construct 2 radii of a circle
and connect them with at the points on the circle with a segment.
2. construct a rhombus ( that includes squares) and construct a diagonal in
either direction.
3. Construct tangents to a circle from a point outside the circle. connect the
tangents at the point of tangency with a segment.
4. Construct a diameter perpendicular to a chord. The diameter bisects the
chord. Connect the endpoints of the chord to the center of the circle and you
have an isosceles triangle. This is similar to using radii (#1), but it takes a
different approach.
5. Construct a right triagle and the median of the segment across from the right
angle. By doing this, you create two isosceles triangles because a median drawn
in this way is equidistant from all vertices.
6. Construct the perpendicular bisector of a segment and and connect the two
endpoints of the segment to a point on the bisector.
