---|---|---|---|---|---|
acute angle | an angle smaller then 90 degrees
🗑
|
||||
congruent angles | equal in measure
🗑
|
||||
coplanar | points and lines in the same plane
🗑
|
||||
midpoint | a point that divides a segment into two congruent segments. it bisects a segemnt.
🗑
|
||||
perpendicular lines | intersect to form right angles
🗑
|
||||
ray | a part of a line that consists of a initial point and all points on the line that lie on one side of the initial point.
🗑
|
||||
space | is the boundless 3-dimensional set of all points
🗑
|
||||
angle | two rays connected at their end points
🗑
|
||||
congruent segments | two segments with the same length
🗑
|
||||
counterexample | a single counter is enough to disprove a conjecture
🗑
|
||||
obtuse angle | an angle larger then 90 degrees
🗑
|
||||
plane | is a flat surface that has no thickness. it extends without end in all directions. you need at least 3 noncollinear points to name a plane.
🗑
|
||||
right angle | an angle that measures exactly 90 degrees
🗑
|
||||
angle bisector | cuts an angle into two congruent angles
🗑
|
||||
conjecture | a conclusion reached through inductive reasoning
🗑
|
||||
inductive reasoning | based on observed patterns
🗑
|
||||
opposite rays | start at the same point and go in opposite directions
🗑
|
||||
point | has no length, width, or thickness, but has a position
🗑
|
||||
segment | a portion of a line between two points, called end points
🗑
|
||||
collinear points | points that lie on the same line
🗑
|
||||
coordinate | the distance and directions from the origin of a number line.
🗑
|
||||
line | has no length, no width, or thickness. it extends without end in two directions.
🗑
|
||||
parallel lines | coplanar lines that do not intersect
🗑
|
||||
postulate | a statement to be true without proof
🗑
|
||||
skew lines | noncoplanar lines that are not parallel and do not intersect
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
