TermDefinition
Altitude of a Triangle A straight line through a vertex and perpendicular to (i.e. forming a right angle with) a line containing the base (the opposite side) of a triangle
Angle bisector theorem Concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
Angle bisector theorem, converse If a point is equidistant from the sides of an angle, then it is on the angle bisector.
Center of a Polygon In a rotation, the point that does not move. The rest of the plane rotates around this one fixed point.
Centroid of a Triangle The point where the three medians of the triangle intersect
Circumcenter of a triangle The point where the three perpendicular bisectors of a triangle meet
Circumscribed A geometric figure that is drawn around another geometric figure so as to touch all its vertices
Conditional probability formula The conditional probability of A given B is denoted by P(A|B) and defined by the formula P(A|B) = P(AB) P(B) , provided P(B) > 0. (see also probability formula)
Experimental probability The ratio of the number of times the event occurs to the total number of trials (see also complement probability, conditional probability, probability, theoretical probability)

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.
