2. Parallel (geometry) - Wikipedia

   en.wikipedia.org/wiki/Parallel_(geometry)

   Line a is a great circle, the equivalent of a straight line in spherical geometry. Line c is equidistant to line a but is not a great circle. It is a parallel of latitude. Line b is another geodesic which intersects a in two antipodal points. They share two common perpendiculars (one shown in blue).

3. Zigzag - Wikipedia

   en.wikipedia.org/wiki/Zigzag

   The trace of a triangle wave or a sawtooth wave is a zigzag. Pinking shears are designed to cut cloth or paper with a zigzag edge, to lessen fraying. [2] In sewing, a zigzag stitch is a machine stitch in a zigzag pattern. [3] The zigzag arch is an architectural embellishment used in Islamic, Byzantine, Norman and Romanesque architecture. [4] [5]

4. Hart's inversors - Wikipedia

   en.wikipedia.org/wiki/Hart's_inversors

   Hart's first inversor, also known as Hart's W-frame, is based on an antiparallelogram.The addition of fixed points and a driving arm make it a 6-bar linkage. It can be used to convert rotary motion to a perfect straight line by fixing a point on one short link and driving a point on another link in a circular arc.

5. Cycloid - Wikipedia

   en.wikipedia.org/wiki/Cycloid

   A cycloid generated by a rolling circle. In geometry, a cycloid is the curve traced by a point on a circle as it rolls along a straight line without slipping. A cycloid is a specific form of trochoid and is an example of a roulette, a curve generated by a curve rolling on another curve.

6. Line (geometry) - Wikipedia

   en.wikipedia.org/wiki/Line_(geometry)

   In geometry, a straight line, usually abbreviated line, is an infinitely long object with no width, depth, or curvature, an idealization of such physical objects as a straightedge, a taut string, or a ray of light. Lines are spaces of dimension one, which may be embedded in spaces of dimension two, three, or higher.

7. Straightedge and compass construction - Wikipedia

   en.wikipedia.org/wiki/Straightedge_and_compass...

   It can only be used to draw a line segment between two points, or to extend an existing line segment. The compass can have an arbitrarily large radius with no markings on it (unlike certain real-world compasses). Circles and circular arcs can be drawn starting from two given points: the centre and a point on the circle. The compass may or may ...
