Set 1
- The three building blocks of geometry are points, lines, and
planes, which are used to create the more complex shapes and
figures studied in geometry. - A line contains an infinite number of points, but it only takes two
pointsto define a line. - A point indicates position.
- A ray starts at a point and extends infinitely. It contains an infinite
number of points. - While two points determine a line, it takes threenon-collinear
points determine a plane. - An angle is made up of two raysthat share a common endpoint.
- A line segment is partof a line that has two endpoints. A line
extends infinitely in both directions.
Set 2
- d.Collinear points are also coplanar. Choice ais not the answer
because noncollinear points determine planes, not a single line of
collinear points. - b.An infinite number of lines can be drawn through one point,
but only one straight line can be drawn through two points. - d.Always assume that in plane geometry a line is a straight line
unless otherwise stated. Process of elimination works well with this
question: Lines have one dimension, length, and no substance;
they are definitely not solid. Lines extend to infinity; they are not
finite. Finally, we defined noncollinear as a set of points that “do
