 AB A straightforward figure the is not identified in state of other figures.You are watching: The common endpoint of an angle Collinear Points the lie ~ above the exact same line. Plane A level surface that has actually no thickness and extends forever. Line A straight path that has no thickness and also extends forever. Point A location that has no size. Coplanar Points that lie in the exact same plane. Endpoint A point at an finish of a segment or the starting point that a ray. Ray A component of a line that starts in ~ an endpoint and extends forever in one direction. Postulate A statement the is embraced as true there is no proof, likewise called one axiom. Vertex The usual endpoint that the political parties of an angle. Opposite rays Two beam that have a usual endpoint and type a line. Segment A part of a line consisting of 2 endpoints and all points in between them. Distance The absolute worth of the difference of the coordinates of two points. Construction A technique of creating a number that is taken into consideration to be mathematically precise. Between Given three points A, B, and C, B is between A and C if and only if all three of the points lie on the same line, and abdominal + BC = AC. Coordinate plane A plane that is divided into four regions by a horizontal line dubbed the x-axis and a vertical line referred to as the y-axis. Coordinate A number used to identify the ar of a point. Congruent segments Two segment that have actually the very same length. Degree A unit of edge measure. Midpoint The suggest that divides a segment right into two congruent segments. Bisect To divide right into two congruent parts. Angle A figure formed by 2 rays v a typical endpoint. Measure The usage of devices to find a dimension or quantity. Segment bisector A line, ray, or segment that 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 measures 180°. Acute angle An angle the measures better than 0° and less than 90°. Right angle An angle that procedures 90°. Interior of one angle The set of every points in between the sides of an angle. Obtuse angle An angle the measures better than 90° and also less 보다 180°. Exterior of an angle The collection of every points external an angle. Adjacent angles Two angles in the same plane with a typical vertex and a usual side, yet no typical interior points. Complementary angles Two angle whose measures have actually a amount of 90°. Supplementary angles Two angle whose measures have a sum of 180°. Angle bisector A ray that divides an angle right into two congruent angles. Linear pair A pair of nearby angles who noncommon sides room opposite rays. Congruent angles Angles that have actually the same measure. Image A form that outcomes from a change of a figure. Preimage The original number in a transformation. Reflection A transformation across a line. Transformation A change in the position, size, or shape of a figure. Rotation A change about a allude P, such that each suggest and its image are the exact same distance native P. Translation A change in which all the clues of a number move the same distance in the very same direction. leg One the the 2 sides that the appropriate triangle that kind the best angle. Area The variety of nonoverlapping unit squares that a provided size the will specifically cover the interior of a airplane figure. Hypotenuse The side opposite the ideal angle in a ideal triangle. Length The distance in between the 2 endpoints the a segment. base Any side of a triangle. Height Asegment from a crest that forms a right angle through a heat containing the base. Radius A segment whose endpoints room the center of a circle and also a suggest on the circle, or the street from the facility of a circle to any point on the circle. Perimeter The amount of the side lengths that a closed plane figure. pi The ratio of the one of a circle come its diameter, denoted by the Greek letter π. Circumference The distance around the circle.See more: Biology Chapter 7 Pho To What Does The Term Grana Refer ?
