TermDefinition
Angle consists of two different rays with the same endpoint. The rays are the sides of the angle, and the endpoint is the vertex of the angle.
Sides of the angle ray where a measurement of an angle starts
Vertex of the angle on a polygon vertices are where adjacent meet,
Protracter postulate
Measure of an angle consider OB and a point A on one side of OB. the rays of the form OA can be matched one to one with the real numbers from 0 to 180. the measure of <AOB is equal to the absolute value of the difference between the real numbers.
Acute angle a triangle with three acute angles
right angle a triangle with one right angle
obtuse angle an angle with measure between 90 and 180 degrees
Straight angle an angle with a measure that is equal to 180 degrees
congruent angle angles that have the same measure
angle bisector a ray that divides an angle into two angles that are congruent
construction a geometric drawing that uses a limited set of tools, usually a compass and straightedge
complementary angle two angles whose measures have the sum of 90 degrees. the sum of the measures of an angle and its complement is 90 degrees
supplementary angle two angles whose measures have the sum 180 degrees. the sum of the measures of an angle and its supplement is 180 degrees.
adjacent angle two angles that share a common vertex and side, but have no common interior points.
linear pairs two adjacent angles whose non common sides are opposite rays
vertical angles two angles whose sides form two pairs of opposite.
polygon a closed plane figure with the following properties.(1) it is formed by three or more line segments called sides.(2) each side intersects exactly two sides, one at each endpoint, so that two sides with a common endpoint are collinear.
sides of a polygon each lne sement that forms a polygon
vertex of a polygon each endpoint of a side of a polygon
convex a polygon such that no line containing a side of the polygon contains a point in the interior of the polygon. a polygon that is not convex is nonconvex or concave
concave a polygon that is not convex
equilateral a polygon with all its sides congruent
equiangular a polygon with all of its interior angles congruent
regular polygon a polygon that has all sides and all angles congruent
formula for a perimeter of a square the distance on the outside of a square
formula for area of a square Area= a x a ( a squared)
formula for perimeter of a rectangle Total distance on the outside of a triangle
formula for area of a rectangle Area= w x h
formula for area of a triangle Area= 1/2 x b x h
formula for circumference of a circle Area= 2 x pi x radius= pi x diameter
formula for area of a circle Area= pi x radius x radius ( radius squared )
