Please rate your understanding of the vocabulary from today (planes, points, lines, collinear, coplanar, line segments, rays, and opposite rays.) I understand the definitions of all terms above and I could explain these topics to others. 4 I am not sure if I understand every word completely, but I have enough confidence to try and figure it out. 3 Some terms make sense, but I need some help understanding others. 2 This is new to me and I cannot define these terms now. 1

See below

Step-by-step explanation:

A plane is a flat, two-dimensional surface that extends infinitely.

A point is a precise location on a plane.

A line is a one-dimensional figure that has only its length that extends infinitely.

Points are collinear if they all fall on the same straight line.

Points or lines are coplanar if they all fall on the same plane.

Line segments are a line with two endpoints on each end of the segment, which have a definite length.

Rays are lines that have one endpoint and the other end of the line extends infinitely with no endpoint.

Opposite rays are two rays that have a common endpoint that point in opposite directions and form a straight line.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
