Trigonometry is a branch of geometry which is primarily concerned with the properties and measurement of triangles.
if you're talking about 2 triangles that overlap, then yes and they are called overlapping triangles. XD
No it can only be used with right angle triangles.
They are similar triangles.
If it is in the form of two inverted triangles, then there are 8 triangles. If only the outline is used, there are 0 triangles.
