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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
