The CRT display becomes an electronic graph of two instantaneous voltages. The display may be a direct comparision of two voltages such as during phase measurement, or frequency measurement with Lissajous waveforms.
All congruent figures are similar figures, and have identical sizes.
3dimentional figures are solid figures.
Congruent figures are figures that have the same size and shape.
For example, figures like C and N are open figures, and figures like O and D are closed.
when 2 perpendicular, sinusoidally varying voltages are applied to an electron beam in a CRT, the pattern traced by the beam on the screen of the CRT is a lissajous figure.
Jules Antoine Lissajous died in 1880.

There is quite a bit info on Lissajous curves(that's spelled right), check the link below.

A: To get the phase angle
a pattern that is produced by adding or subtracting signals in or out of phases is called lissagious pattern.It is the type of pattern that is produced on the screen of an oscilloscope.by ADDING OR SUBTRACTING SIGNALS IN-OUT OF PHASES CAUSES A LISSAJOUS PATTERN. This is caused by comparing phases any magnitude if equal and set out of 90 degrees will be a circle on a Lissajous patter.
If you must use an oscilloscope, then using Lissajous Figures will give you exact multiples of a given frequency. Naturally, you must have a known reference frequency at hand.These days a Frequency Counter will give adequate resolution.
