A measurable part of a line consisting of two endpoints.
What is a line segment?
The formula used to find the midpoint between two endpoints.
What is the midpoint formula- (x1 + x2)/2, (y1 + y2)/2
Adjacent angles that are supplementary and that form a straight line.
What is a linear pair?
The midpoint of segment HK given H(-1, 2) and K (-7, -4)
What is (-4, -1)
This is AB if A(2, 0) and B(6, 3)
What is 5?
A location with no size or shape
What is a point?
The formula used to find the distance between 2 points on a coordinate plane.
What is the distance formula? (square root (x2 - x1)^2 + (y2 -y1)^2
Two angles with measures that add to 90 degrees
What is complementary?
S is the midpoint of RT.
This is T if R (-9, 4) and S(2, -1)
What is (13, -6)
This is BC if B(8, -7) and C(-4, -2)
What is 13?
Points that lie on the same line.
What is collinear?
If A, B and C are collinear points, and B is between A and C then AB + BC = AC
What is the segment addition postulate?
Two angles that are directly across from each other in intersecting lines. Their measures are congruent.
What are vertical angles?
This is the midpoint of the segment with these endpoints: (5, 8) and (-1, -4)
What is (2,2)?
This is ST if S(-3, 10) and T(-2, 3). Round to nearest tenth.
What is 7.1?
Points that do NOT lie on the same plane.
What is non-coplanar?
The "rise" of a directed line segment
What is difference between ys y2 - y1?
If angle ABD and angle DBC are adjacent, then angle ABD + angle DBC = angle ABC
What is the angle addition postulate.
The midpoint of segment HK given H(-1, 2) and K (-7, -4)
What is (-4, -1)
If P(-5, -1) and Q(-2, -4), this is the distance between P & Q (round to nearest tenth)
What is 7.6?
Made up of points with no thickness or width
What is a line?
The "run" of a directed line segment
What is horizontal change? x2 - x1
Two lines that intersect at right angles.
What are perpendicular lines?
The coordinates of Z if Y is the midpoint of segment XZ, X(-10, 9) and Y(-4, 8)
What is (2, 7)?
The distance between (-4,6) and (3,-7) rounded to the nearest tenth
What is 14.8?
