True
Not true.
FALSE
False. It is not possible to trisect any arbitrary angle using only a compass and straightedge, as proven by Pierre Wantzel in 1837. While some specific angles can be trisected using these tools, the general case of angle trisection is one of the classic problems of ancient geometry that cannot be solved with these methods.
Its true just got it wrong
false apex The Greeks used a straightedge and a compass

True
Not true.
FALSE
Maybe, but a straight edge and a pair of compasses would have probably been used to construct a perpendicular line bisector for a given line segment.

To construct pyramids; the pyramids were constructed in Ancient Egypt.

to construct (using a compass and straight-edge) a square with the same area as a given circle using only a finite number of steps. "Squaring the circle" was an ancient problem that has been proved impossible to do.
