A series of points along a
Two points on the major axis
Two points on the minor axis
When you use the foci method of
constructing an ellipse, what is your second
Locating the axes
Locating the center
Locating the foci
Locating the measurement of one half
the major axis
Refer to figure 2-47 in the TRAMAN. To
plot the second set of points on the
circumference of an ellipse, where do you
position the compass?
Points CB2 and DB2
Points F and F1
What drawing tool should you use to plot a
series of points to construct an ellipse?
The diameters of the concentric circles
represent what element of an ellipse?
The major and minor axes
Using the conjugate diameter method of
ellipse construction, the initial two lines
drawn are the diameters of the concentric
circles perpendicular to each other.
