Question
Answer
Acute Angle   An angle with measure between 0 degrees and 90 degrees.  
🗑
Adjacent Angles   Two angles with a common vertex and side but no common interior points.  
🗑
Angle   Consists of two different rays that have the same initial point.  
🗑
Angle Bisector   A ray that divides an angle into two adjacent angles that are congruent.  
🗑
Bisect   To divide into two congruent parts.  
🗑
Collinear   Points that lie on the same line.  
🗑
Compass   A construction tool used to draw arcs.  
🗑
Complementary Angles   Two angles whose measures have the sum of 90 degrees.  
🗑
Congruent Segments   Segments with the same length.  
🗑
Coplanar   Points, lines, rays, or segments that lie in the same plane.  
🗑
intersect   To have one or more points in common.  
🗑
line   Exists in one dimension and extends without end in opposite directions.  
🗑
linear pair   Two adjacent angles whose non common sides are opposite rays.  
🗑
midpoint   A point that bisects a segment into two congruent parts.  
🗑
obtuse angle   An angle with measure between 90 degrees and 180 degrees.  
🗑
plane   Exists in two dimension and extends in all directions without end.  
🗑
point   A location that has no dimension.  
🗑
ray   Part of a line that consists of an initial point and all points extending from that point.  
🗑
segment   Part of a line that consists of two endpoints and all the points between.  
🗑
supplementary angles   Two angles whose measures have the sum of 180 degrees.  
🗑
vertical angles   Two angles whose sides form two pair of opposite rays.  
🗑
Linear Pair Postulate   If two angles form a linear pair, then they are supplementary.  
🗑
Vertical Angles Theorem   Vertical Angles are Congruent.  
🗑
theorem   A true statement that follows as a result of other true statements.  
🗑
Geometry   The mathematics of the properties, measurement, and relationships of points, lines, angles, surfaces, and solids.  
🗑
opposite rays   Two rays that have a common endpoint and form a straight line.  
🗑
pi   The ratio of Circumference to diameter.  
🗑
postulate   A geometry rule that is excepted as true without proof.  
🗑
reflection   A transformation across a line in which the image is the same distance from the line as the preimage.  
🗑
transformation   A change in the position, size or shape of a figure.  
🗑


   

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.
