Unit 1 Geometry

Essential Geometry Baldwin County

TermDefinition
Acute Angle An angle with measure between 0 degrees and 90 degrees.
Adjacent Angles Two angles with a common vertex and side but no common interior points.
Angle Consists of two different rays that have the same initial point.
Angle Bisector A ray that divides an angle into two adjacent angles that are congruent.
bisect To divide into two congruent parts.
collinear points Points that lie on the same line.
compass A construction tool used to draw arcs.
complementary angles Two angles whose measures have the sum of 90 degrees.
congruent segments Segments with the same length.
coplanar points Points, lines, rays, or segments that lie in the same plane.
intersect To have one or more points in common.
line Exists in one dimension and extends without end in opposite directions.
linear pair Two adjacent angles whose non common sides are opposite rays.
midpoint A point that bisects a segment into two congruent parts.
obtuse angle An angle with measure between 90 degrees and 180 degrees.
plane Exists in two dimension and extends in all directions without end.
point A location that has no dimension.
ray Part of a line that consists of an initial point and all points extending from that point.
segment Part of a line that consists of two endpoints and all the points between.
supplementary angles Two angles whose measures have the sum of 180 degrees.
vertical angles Two angles whose sides form two pair of opposite rays.
Linear Pair Postulate If two angles form a linear pair, then they are supplementary.
Vertical Angles Theorem Vertical Angles are Congruent.
theorem A true statement that follows as a result of other true statements.
Geometry The mathematics of the properties, measurement, and relationships of points, lines, angles, surfaces, and solids.
opposite rays Two rays that have a common endpoint and form a straight line.
postulate A geometry rule that is excepted as true without proof.
polygon A closed plane figure with 3 or more line segments called sides and each side intersects exactly two sides. No two sides are collinear.
convex A polygon with all its interior angles less than 180°.
concave Non-convex polygon.
equilateral Polygon with all sides congruent.
equiangular Polygon with all angles congruent.
regular polygon A convex polygon that is both equilateral and equiangular.

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.
