 AB A basic figure the is not defined in state of various other figures.You are watching: The region of a plane inside of an angle Collinear Points that lie ~ above the exact same line. Plane A level surface that has actually no thickness and extends forever. Line A straight course that has no thickness and also extends forever. Point A location that has no size. Coplanar Points that lie in the same plane. Endpoint A suggest at an finish of a segment or the beginning point of a ray. Ray A part of a line the starts at an endpoint and extends forever in one direction. Postulate A statement that is embraced as true without proof, likewise called an axiom. Vertex The typical endpoint the the political parties of one angle. Opposite rays Two beam that have actually a typical endpoint and form a line. Segment A part of a line consisting of two endpoints and all points in between them. Distance The absolute value of the difference of the works with of 2 points. Construction A method of producing a number that is taken into consideration to it is in mathematically precise. Between Given three points A, B, and C, B is between A and C if and only if all 3 of the point out lie top top the exact same line, and abdominal muscle + BC = AC. Coordinate plane A aircraft that is split into four regions through a horizontal line called the x-axis and a upright line referred to as the y-axis. Coordinate A number supplied to recognize the location of a point. Congruent segments Two segment that have actually the very same length. Degree A unit of edge measure. Midpoint The allude that divides a segment right into two congruent segments. Bisect To divide right into two congruent parts. Angle A number formed by 2 rays with a common endpoint. Measure The usage of units to discover a dimension or quantity. Segment bisector A line, ray, or segment the divides a segment right into two congruent segments. Vertical angles The nonadjacent angles developed by 2 intersecting lines. Straight angle An angle developed by 2 opposite rays that procedures 180°. Acute angle An angle that measures higher than 0° and less 보다 90°. Right angle An angle that steps 90°. Interior of an angle The collection of every points in between the political parties of one angle. Obtuse angle An angle that measures greater than 90° and less than 180°. Exterior of one angle The collection of every points external an angle. Adjacent angles Two angles in the same plane with a usual vertex and a common side, however no typical interior points. Complementary angles Two angle whose measures have a amount of 90°. Supplementary angles Two angle whose measures have actually a amount of 180°. Angle bisector A ray that divides an angle right into two congruent angles. Linear pair A pair of surrounding angles who noncommon sides are opposite rays. Congruent angles Angles that have the very same measure. Image A form that outcomes from a change of a figure. Preimage The original number in a transformation. Reflection A change across a line. Transformation A adjust in the position, size, or shape of a figure. Rotation A transformation about a point P, such the each point and its photo are the same distance indigenous P. Translation A change in which every the point out of a number move the very same distance in the very same direction. leg One that the two sides of the appropriate triangle that form the best angle. Area The variety of nonoverlapping unit squares the a provided size that will precisely cover the interior of a plane figure. Hypotenuse The next opposite the right angle in a ideal triangle. Length The distance between the 2 endpoints that a segment. base Any side of a triangle. Height Asegment native a peak that develops a right angle v a heat containing the base. Radius A segment who endpoints room the center of a circle and also a suggest on the circle, or the street from the facility of a circle come any point on the circle. Perimeter The sum of the next lengths the a closed airplane figure. pi The proportion of the one of a circle to its diameter, denoted by the Greek letter π. Circumference The distance about the circle.See more: How Does Seaweed Survive In The Ocean S?
