Geometry

For math

TermDefinition
Circumference C=2pi r or C=pi d
Pi ≈3.14 or ≈22/7
Triangle Polygons with three sides, three angles, three vertices
Equilateral All sides congruent
Isoscles At lest two side congruent
Scalene No sides congruent
Equangular All angles congruent
Point A geometric object that has no dimensions, only a location
Plane at surface that extends endlessly in all directions; two dimentional
Space the set of all points;three dimentional
Line A set of points along a straight path having no endpoints
Line segment Pair of a line that has two endpoints
Ray Part of a line that only has one endpoint
Angle two rays jointed together with a common endpoint; the two rays are called the sides of an angle
Vertex The common endpoint for an angle
Intersecting lines Lines that have just one point in common
Supplementary angles Two angles whose measure adds up to 180 degrees; any two right angles are supplementary
Complementary angles Two angles whose measure adds up to 90 degrees
Transversal A line that intersects two other lines
Adjacent angles Two angles that share a side ( or ray ) and a vetex
Skew lines Lines that are not in the same plane and do not intersect
Equilateral polygon All sides congruent
Equiangular Polygon All angles congruent
Parallelogram Quadrilaterral with both pairs of opposite sides parallel
Corresponding angles Two lines intersected by a transversal form corresponding pairs of angles; if the lines are parallel the corresponding pairs of angles are congruent
n- gon 180(n-2)

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.
