Using the 2 radii of a circle.
(radii of a circle are congruent)

Drop a diagonal through a rhombus.
(sides of a rhombus are congruent)

Take 2 congruent circles and construct a point at their intersection. Connect
thier pt. of intersection with the radii.
( congruent triangles have congruent radii.)

Take any segment and find it's midpoint. Draw a perpendicular segment at the
midpoint. Connect the points to make the congruent legs of the Æ.
(If the point lies on the perpendicular bisector of a segment, then the point is
equidistant from the endpoints of the segment)

Construct a circle and two of it's tangents. Construct a point at their
intersection.
(tangents to a circle from a point are congruent)

Construct a square and drop it's diagonal.
(sides of a square are congruent)

Construct a rectangle and it's diagonals.
(diagonals of a rectangle are congruent and bisect each other)

Construct a square and it's diagonals.
(diagonals of a square are congruent and bisect each other)
