Across
2.For two lines intersected by a transversal, a pair of angles that lie on opposite sides of the transversal and outside sides of the transversal and outside the other two lines.
8.Lines that intersect at 90 degree angles.
9.Lines that don't intersect.
11.A line that divides a line segment into two equal parts.
12.The difference in the y-values of two points on a line.
13.For two lines intersected by a transversal, a pair of nonadjacent angles that lie on opposite sides of the transversal and between the other two lines.
14.y=mx+b
15.A rising or falling surface.
16.Lines that aren't coplanar.
Down
1.The length of the perpendicular segment from the point to the line.
3.Two angles lying on the same side of the transversal cutting across two parallel lines.
4.Planes that don't intersect.
5.A line that intersects two coplanar lines at two different points.
6.the angles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
7.The equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line
10.The difference in the x-values of two points on a line.
