Epicycloid epicycloid is the curve generated by the trajectory of a point of a circumference that rolls without sliding on the outside of another guideline circumference. We draw both circumferences tangentially. Center of the center of the we divide the generating circle in equal parts in this is calculated the central angle of the base circumference according to the formula where is the radius of the generatrix the radius of the guideline. We divide an angle of the guideline equal to that found in the same quantity of parts. Defining the points on the circumference we draw lines from the previous points. We draw an arc of length with center in which cut the previous lines in which they will be the successive centers that will occupy the generating circumference. By the points dividing the tracing arcs with center in which they will cut auxiliary circumferences in points that will determine the epicycle. With centers in tracing the mentioned auxiliary circumferences. In the following way we will find the points of the epicycloid: the circumference with center in the intersects with the arc plus the circumference with center in with the one so that it intersects with the outer one more then we go inwards again until of that way we have the points Which by joining them form the epicycloid., Ovoid given the non-symmetric axis we take this axis as diameter of a circle of center of we draw a perpendicular that cuts the circumference in touching this point we draw two lines the points will be centers of the arcs of radius ab respectively. With which we conclude the construction of the desired ovoid., Hypocycloid Hypocycloid is a curve described by a point on a circle that rolls without through the inside of another circumference. Construction given the circumferences generatriz guideline q. The generatrix circumference has in this particular case a third of the radius of the guideline circumference q. The generatrix circumference is divided into several parts because they are located on the circumference giving parts that will have hypocycloids. With center in it are described circumferences with centric that pass by the divisions of the circumference as well as by its center the end of the diameter ab. The radii that cut the circumference of radius at the points respectively are drawn. From these points with radius ob are described arcs that cut the concentric circles described from the points that are the points through which the hypocycloids pass., Ovalo the oval is a crushed circle that resembles an ovoid shape its shape does not deviate much from that of a circumference one usually have one two axes of symmetry. Construct draw an axis trace the perpendicular bisector of the ab axis. Determine the points of intersection of the line with the circumference of center diameter ab. Draw the lines of origin in that contain the points that will limit the arcs of circumferences that make up the oval. Draw the arcs of circles that have centers at the points of radius ab. With centers in tracing the arcs of circumferences that spliced ​​with the two already completing the oval., axis, Parabola: to make a parabola we will use the method of projective beams. Given the vertex axis a point in the parabola. Plot the axis locate the vertex the given point. Draw the rectangle pqvr. Divide pq pr into the same number equal parts number from the point p. Tracing the originals that contain the points given by the line pq. Draw lines parallel to the axis that pass through the points on the pr line. The points of intersection of the semirectas with the lines that have with the points numbered with the miso digit determine the points of the parabola. Locate the symmetrical point to the point with respect to the axis repeat the procedure to complete the path., axis, To trace a horizontal axis locate the vertices also a lower top point draw a rectangle this case divide pq pr into a same number of equal parts we enumerate from p. Draw the half-lines from the points divided into pq. Draw the half-lines from the points divided into pr. Joining the points of intersection of the half-faces with it determine the hyperbola. We locate a point p ‘symmetric of respect to the axis to repeat the same procedure to find the other branch of the hyperbola., Involutes is the spiral described by a point of a thread that remains tense. The thread may be wound around a segment of any regular polygon of any circumference. Construction when drawing a line segment. Alternately centering at the ends of the radii starting with the length of the segment continuing with the distances that result each as seen in the figure., Cycloid the cycloid is the generated curve
