|---|---|---|---|---|---|
| Point | A point has no dimension. It is usually represented by a dot.
🗑
|
||||
| Plane | A plane has two dimensions. It is usually represented by a shape that looks like a floor or wall.
🗑
|
||||
| Ray | Part of a line that consists of a point called an endpoint and all points on the line that extend in one direction.
🗑
|
||||
| Vertical Angles | Two angles whose sides form two pairs of opposite rays.
🗑
|
||||
| Angle Bisector | A ray that divides an angle into two angles that are congruent.
🗑
|
||||
| Angle | : Consists of two different rays with the same endpoint. The rays are the sides of the angle and the endpoint is the vertex of the angle.
🗑
|
||||
| Collinear Points | Points that lie on the same line.
🗑
|
||||
| Coplanar Points | Points that lie on the same plane.
🗑
|
||||
| Adjacent Angles | Two angles that share a common vertex and side, but have no common interior points.
🗑
|
||||
| Opposite Rays | Two rays with a common endpoint that point in opposite directions.
🗑
|
||||
| Line | A line has one dimension. It is usually represented by a straight line with two arrowheads to indicate that the line extends without end in two directions.
🗑
|
||||
| Line Segment | : Part of a line that consists of two points, called endpoints, and all points on the line that are between the endpoints.
🗑
|
||||
| Linear Pair | Two adjacent angles whose non-common sides are opposite rays.
🗑
|
||||
| Obtuse Angle | An angle with measure between 90 and 180 degrees.
🗑
|
||||
| Right Angle | An angle with measure equal to 90 degrees.
🗑
|
||||
| Non-Coplanar Points | Points that do not lie on the same plane.
🗑
|
||||
| Non-Collinear Points | Points that do not lie on the same line.
🗑
|
||||
| Supplementary Angles | Two angles whose measures have the sum 180 degrees. The sum of the measures of an angle and its supplement is 180 degrees.
🗑
|
||||
| Complementary Angles | : Two angles whose measures have the sum 90 degrees. The sum of the measures of an angle and its complement is 90 degrees.
🗑
|
||||
| Vertex | The same endpoint of two rays that form an angle.
🗑
|
||||
| Acute Angle | An angle whose measure is between 0 and 90 degrees.
🗑
|
||||
| Straight Angle | An angle whose measure is 180 degrees.
🗑

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.
