True or False? (these are confusing me...am i right for the ones I answered?)
-7 is a square root of 49 F
|-x|=|x| T
If PQ = QR, then Q is the midpoint of segment PR.
If a segment is entirely contained in S, then S is a convex set.
If A, B, and C are three collinear points and AB<AC, then A-B-C
On the line PR the coordinate of point P is 17 and the coordinate of R is -6. Then PR = |17-6|. T
If two planes are not parallel, they must intersect T
If three points are collinear, they are coplanar T
A point and a line always lie in exactly one plane. F
Fill in the blank w/ always, never, or sometimes (answers by me are bolded)
Two points sometimes lie in exactly one plane
Two intersecting lines sometimes lie in exactly one plane
Two lines that are not coplanar never intersect
A half plane never contains its edge
Four points, three of which are collinear, are never coplanar
Three lines intersecting in one point are sometimes coplanar
Are rays, lines, squares, planes, and circles all a convex set? YES <--- is that right?
The intersection of two rays may be a segment? line? ray? point? an empty set? point <--- is that right and is it only a point or can it be something else?
