Random
Any location identified by a capital letter. It can be anywhere and be used in so many different ways. You can usually see them living on lines and planes.
A point
A straight line, with a ending point and a starting point. (does not extend infinitely)
Line segment
An angle is an angle that is less than 90 degrees. An angle is formed by two rays which intersect at their endpoints which are combined to create the vertex.
Acute Angle
What formula is this?
?=sqrt of (x2 - x1)^2 + (y2 - y1)^2
Distance Formula
They are line segments that connect to many points, creating a shape.
It is a little different from a regular point. It has all the same properties besides equally cutting the line segment in half.
Midpoint
These lines extend infinitely and even though they are not parallel they still will never intersect.
Skew Lines
Is made out of two endpoints that extend outwards forming never-ending-rays.
Vertex
What is the midpoint of (3, 2) and (6, 10)
(2.5, 8)
A one dimensional object that has no width, depth or curvature. It extends infinitely in 2 opposite directions.
Line
An area/dimension that extends infinitely in all directions. It is a flat surface made out of 4 points.
Plane
Is almost like a combination of a line and a line segment. It only has one endpoint and the other side extends infinitely.
Ray
It is made out of two rays that meet and create a vertex and create an angle that is over 90 degrees.
Obtuse Angle
What formula is this?
(xm, ym) = ((x1+x2 divided by 2) , (y1+y2 divided by 2))
Midpoint formula
They help us identify whether or not a line is a bisector. If they are present it means that the other line has split the line in half. If they are not there we cannot assume that the two line segments are equal.
Hash marks
It is when two objects or figures are the same size and shape. They can be seen as mirror images of each other.
congruence
Lines are lines that will never intersect. They will continue to live side by side on the same plane/dimension.
Parallel Lines
A unit of measurement. We use it to measure angles to find out whether or not its obtuse, right, or acute. We can also use them for creating angles ourselves.
Degrees
What is the distance between
(3, 2) and (6, 10)
d=sqrt of 73
A point that is at the start or end of a line segment. It usually is connected to another one of its own but it could also be connected to a ray.
Endpoint
Two lines that intersect, splitting the line into two equal side lengths.
Bisector
These lines are intersecting creating two pairs of 90 degree angles.
Perpendicular Lines
It is made out of two rays which their endpoints meet at the vertex, creating a 90 degree angle. If the angle does not have the little box at the vertex, you cannot assume, even if it looks like one.
Right Angle
BONUS
What formula is this
2(pi)r=(pi)d
Circumference of a circle
They are line segments that connect to many points, creating a shape.
