Midpoints and Bisectors,
What is a Midpoint?
It is a point that lies halfway between 2 other points.
How do you define a point in geometry?
A location
What is the formula for the distance problem?
d=r t
What is a line segment?
A line segment is represented by endpoints on each end of the line segment.
What is a bisector?
A line that divides a line or an angle into two equivalent parts.
How long does a line segment go on for?
It goes on forever.
What is the distance term in a distance formula?
D = (Speed x Time)
Does a line segment have 2 arrows above or only one going left?
2 arrows
How to find the midpoint?
You use the midpoint formula
What is a plane?
A falt surface or area that extends infinitely in two dimensions and has no thickness.
What is the term time in the distance formula?
Time=DistanceSpeed
What is a ray?
A line with a single endpoint that extends infinitely in one direction.
What is the midpoint of the line segment with endpoints (2, -4) and (6,10)?
(4,7)
What is the equation of a plane that passes through the point (2,-1,3) and is perpendicular to the vector (1,4,-2)
x+4y-2z=-8
When do we use the distance formula?
To find the distance between points in a plane.
Does a ray extend forever?
Extends on forever in the opposite direction.
How do bisectors work?
A ray that divides an angle into two equal parts.
What are the 7 types of lines?
- Straight line
- Curved line
- Vertical line
- Parallel line
- Intersecting line
- Perpendicular line
- Line and rays
Why do we use the distance formula?
To find the length of a line segment between two points on a graph.
What is the difference between a line segment and a ray?
A line segment is part of a line with two end points. A ray is a part of a straight line that extends only in one direction from a fixed point.
