Undefined Terms
As an indicator of location, this undefined term is left with no dimension.
The distance between points U (1,3) and B (4,6) is
What is 3 radical 2?
Most people have heard that parallel lines will never intersect, but these lines must also live on the same flat surface, otherwise known by this geometric term.
coplanar
Unlike parallel lines, perpendicular lines intersect and specifically form four equal angles, each measuring this many degrees.
90
This type of transformation produces an image that is congruent to its pre-image.
Rigid Motion, Congruence Transformation
The intersection of two planes is:
If a point is the midpoint, then it does this to a line segment.
Divides the segment into two, congruent parts
Equal/Same
The symbol for "is perpendicular to" looks like this letter, but upside down.
The letter T
This transformation is not a rigid motion even though it produces an image whose corresponding angles are congruent.
Dilation
A set of infinite points, or defined by two points:
Line
The midpoint between (0,6) and (0,4),
(0,5)
A line that crosses two lines at two distinct points is called this (whether there's parallel lines or not).
Transversal
The slopes of perpendicular lines are....
negative reciprocals
When you reflect across the x-axis for point A (-5, 7)
A ' (-5, -7)
A set of infinite lines forming a flat surface
Plane
(-2, -1)
When lines are parallel, these angles are congruent and can be found in the corners of a letter Z that can be formed within the diagram.
Alternate Interior Angles
The slopes of perpendicular lines have a product of -1 except when it's these two types of lines. One of which has a slope of 0 while the other doesn't even have one.
horizontal and vertical lines
This congruence transformation spins objects about a center, by a specific amount of degrees.
Rotation
The intersection of lines is called:
What is a point?
The length of the line segment connecting (9,2) and (1,8) to the nearest tenth unit on the coordinate plane. 10.0
10.0
If angle A is x + 3 and angle E is 7x +1, and angle A and E are consecutive interior angles. What is the value of x?
x = 22
The slope of a line perpendicular to y=4x-1
