When are two triangles said to be in perspective?
a.
If the corresponding vertices of two triangles form three lines that intersect in a single point
c.
If the corresponding vertices of four triangles form three lines that intersect in a single point
b.
If the corresponding vertices of three triangles form three lines that intersect in a single point
d.
If the corresponding vertices of two triangles form three lines that intersect in two points.
Two triangles are said to be in perspective from a point, O if the corresponding vertices of the two triangles form three lines that intersect in that single point, O. The two triangles can also be described as homologic from point, O.
