MORE geometry true or false???

15. Through a given point on a line there is one and only one line perpendicular to the given line.

16.In every triangle there is exactly one right angle. (i know this one is fALSE!!)

17.Through a point not on a line, one and only one line can be constructed parallel to the given line.

18. If CA = AT, then A is the midpoint of CT.

19. If m

15) true

16)false but the 3 angles add to 180, cant have more than one right angle

17)true

18) holds if and only if A lies on the line CT

take the triangle with points CAT

CA can =AT but A not midpoint

19) if I remember right the linear pair needs to add to 180

15 & 17 assume planar geometry would be different if mapped onto a sphere or hyperbola

18. Can you think of an example where this is NOT necessarily true?
