 AB A simple figure the is not identified in terms of other figures.You are watching: A figure formed by two rays that have the same endpoint Collinear Points the lie top top the same line. Plane A level surface that has actually no thickness and extends forever. Line A straight course that has actually no thickness and extends forever. Point A place that has no size. Coplanar Points that lie in the very same plane. Endpoint A suggest at an finish of a segment or the starting point that a ray. Ray A part of a line the starts at an endpoint and extends forever in one direction. Postulate A statement that is welcomed as true without proof, also called one axiom. Vertex The typical endpoint of the sides of one angle. Opposite rays Two light ray that have a common endpoint and type a line. Segment A component of a line consisting of 2 endpoints and also all points between them. Distance The absolute value of the distinction of the works with of 2 points. Construction A method of developing a figure that is considered to be mathematically precise. Between Given 3 points A, B, and C, B is in between A and C if and only if all three of the clues lie ~ above the same line, and abdominal muscle + BC = AC. Coordinate plane A aircraft that is split into four regions through a horizontal line referred to as the x-axis and a upright line called the y-axis. Coordinate A number used to recognize the ar of a point. Congruent segments Two segment that have actually the exact same length. Degree A unit of edge measure. Midpoint The allude that divides a segment into two congruent segments. Bisect To divide into two congruent parts. Angle A number formed by 2 rays with a common endpoint. Measure The usage of devices to uncover 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 formed by two intersecting lines. Straight angle An angle developed by 2 opposite beam that actions 180°. Acute angle An angle that measures higher than 0° and also less 보다 90°. Right angle An edge that actions 90°. Interior of an angle The set of every points in between the political parties of one angle. Obtuse angle An angle that measures better than 90° and also less 보다 180°. Exterior of an angle The collection of every points outside an angle. Adjacent angles Two angle in the same aircraft with a typical vertex and a typical side, yet no usual interior points. Complementary angles Two angle whose measures have actually a sum of 90°. Supplementary angles Two angle whose measures have a amount of 180°. Angle bisector A beam that divides one angle right into two congruent angles. Linear pair A pair of surrounding angles who noncommon sides room opposite rays. Congruent angles Angles that have the same measure. Image A shape that results from a revolution of a figure. Preimage The original figure in a transformation. Reflection A revolution across a line. Transformation A adjust in the position, size, or form of a figure. Rotation A change about a point P, such that each allude and its photo are the exact same distance from P. Translation A change in which every the points of a number move the same distance in the exact same direction. leg One of the 2 sides of the right triangle that type the best angle. Area The variety of nonoverlapping unit squares the a offered size that will exactly cover the internal of a plane figure. Hypotenuse The next opposite the right angle in a ideal triangle. Length The distance in between the 2 endpoints that a segment. base Any side of a triangle. Height Asegment native a peak that forms a ideal angle with a heat containing the base. Radius A segment whose endpoints room the facility of a circle and a point on the circle, or the distance from the facility of a circle come any suggest on the circle. Perimeter The sum of the side lengths of 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 roughly the circle.See more: In A Formal Outline What Should Roman Numerals Represent, Access Denied Diameter A segment the passes through the center of a circle and whose endpoints space on the circle, or the size of together a segment. .tags a { color: #fff; background: #909295; padding: 3px 10px; border-radius: 10px; font-size: 13px; line-height: 30px; white-space: nowrap; } .tags a:hover { background: #818182; } Home Contact - Advertising Copyright © 2021 ptcouncil.net #footer {font-size: 14px;background: #ffffff;padding: 10px;text-align: center;} #footer a {color: #2c2b2b;margin-right: 10px;}
