Question
Answer
Acute Angles   An angle that is less than 90 degrees  
🗑
Congruent Angles   Angles that are the same to each other  
🗑
Coplanar   Points and lines on the same planes  
🗑
Midpoint   A point that divides a segment into two congruent segments. It BISECTS the segment.  
🗑
Perpendicular Lines   Lines that intersect to form right angles  
🗑
Ray   A part of a line that consists of an intial point and all points on the line that lie on the side of the point  
🗑
Space   Boundless 3-dimensional set of all points  
🗑
Angle   Two rays connected at their endpoints where they connect is the VERTEX  
🗑
Congruent Segments   two segments with the same length  
🗑
Counterexample   enough information to disapprove a conjecture  
🗑
Obtuse Angle   An angle more then 90 degrees  
🗑
Plane   Flat surface that has no thickness, it extends without and in ALL directions  
🗑
Right Angle   An angle that is exactly 90 degrees  
🗑
Angle Bisector   Cuts and angle into two congruent angles  
🗑
Conjecture   Is a conclusion reached through inductive reasoning  
🗑
Inductive Reasoning   Is reasoning based on observed petterns  
🗑
Opposite Rays   Start at the same point....and go in different 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   A number that is associated with a point on a line  
🗑
Line   Has no length, width, or thickness. It extends without ends in two directions  
🗑
Parallel Lines   Lines that never meet  
🗑
Postulate   The distance between any two points on a number line is the absolute value of the difference of the corresponding numbers  
🗑
Skew Lines   Are noncoplanar lines. Therefore, they 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.
