Geometry C1

TermDefinition
point a location in space that is represented by a dot and has no dimension.
line one dimencional geometric figure that extends in two opposite directions without end.
plane a flat surface made up of points that has two dimensions and extends without end and is represented by a shape that looks like a floor or wall
endpoints points that represent the ends of line segment or ray.
ray a geometric figure that consists of the endpoint A and all points on line AB that lie on the same side of point A as point B.
intersection the set of points two or more geometric figures have in common.
postulante/axiom a rule that is accepted without proof.
midpoint the point that divides a segment into two congruent segments.
segment bisector a point, ray, line, line segment, or plane that intersects a segment at ist midpoint.
convex polygon a polygon in which no line that contains a side of the polygon contains a point in the interior of the polygon.
concave polygon apolygon in which at least one line that contains a side of the polygon contains a point in the interior of the polygo.
polygon a closed plane figure formed by three or move line segments.
acute angle an angle that has a measure greater than 0 and less than 90.
right angle an angle that has a measure of 90.
obtuse angle an angle that has a measure greater than 90 and less than 180.
straight angle an angle that has a measure of 180.
angle bisector a ray that divides an angle into two angle that are congruent.
complementary angles two angle whose measures have a sum of 90.
supplementary angles two angle whose measures have a sum of 180
adjacent angle two angles that share a common vertex and side but have no common interior points.
vertical angles two angles whose sides form two pairs of opposite rays.
undefined terms words that do not have a formal definitions but there is agreement about what they mean. (point, line, plane)
collinear points points that lie on the same line.
coplanar points points that lie on the same plane
defined terms terms that can be decribed using known words such as point or line.
segment consists of two endpoints and all the points between them.
opposite rays rays that start at the same point but go away from each other creating a straight line.
coordinate a real number that corresponds to a point on a line.
distance the absolute value of the difference of two coordinates on a line.
construction a geometric drawing that uses a limited set of tools, usually a compass and straightedge.
congruent segments line segments that have the sema length.
between when three points are collinear, one point is between the other two.
vertex of an angle the common endpoint of two rays.
angle a set of points consisting of two different rays that have the same endpoint.
sides of an angle the rays of an angle.
interior of an angle the region that contains call the points between the sides of the angle.
exterior of an angle angle that form linear pairs with the interior angle of a polygon.
measure of an angle the absolute value of the difference between the real numbers matched with the two rays tha form the angle on the protractor.
linear pair two adjacent angle whose noncommon sides are opposite rays.

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.
