QuestionAnswer
Transversal A line that intersects two coplanar lines at two distinct points
Segment The part of a line consisting of two endpoints
Coplanar Points and lines that lie on the same plane
Adjacent Two coplanar angles with a common side, a common vertex, and no common points
Midpoint A point ona segment that divides a segment into two congruent segments
Concave A polygon with at least one diagonal that falls outside the polygon
Complementary Two angles whose measures have a sum of 90 degrees
Obtuse An angle whose measure is greater than 90 degrees
Corresponding Two angles that are in the same position on a transversal
Straight An angle whose measure is equal to 180 degrees
Skew Two or more noncoplanar lines
Hypotenuse The longest side of a right triangle
Orthocenter The point of concurrency of the altitudes of a triangle
Parallel Two or more coplanar lines that do not intersect
Centroid The point of concurrency of the medians of a triangle
Altitude The perpendicular segment from a vertex to the line containing the opposite side
Supplementaty Two angles whose measure have a sum of 180 degrees
Median A segment in a triangle whose endpoints are a vertex and the midpoint of the opposite side
Acute An angle whose measure is less than 90 degrees
Concurrent When three or more lines intersect at one point
Circumcenter The point of concurrency of the perpendicular bisectors of a triangle
Vertical Two angles whose sides form two pairs of opposite rays
Convex A polygon with no diagonals that lie outside the polygon
Polygon A closed plane figure with at least three sides that are segments, the sides only intersect at their endpoints
Inverse Negates both of the hypothesis and conclusion of a conditional
Contrapositive Switches the hypothesis and the conclusion and negates both of them
Converse Switches the hypothesis and conclusion in an "if-then" statement
Incentor The point of concurrency of the angle bisectors of a triangle
Conditional Another name for an "if-then" statement
Midsegment A segment in a triangle connecting the midpoints of two sides
Regular A polygon with all sides and angles the same
Right An angle whose measure is equal to 90 degrees
CPCTC Used to prove angles or sides of triangles are congruent

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.
