 AB A an easy figure that is not defined in state of various other figures.You are watching: A part of a line that starts at one endpoint and extends forever Collinear Points that lie ~ above the very same line. Plane A level surface that has no thickness and also extends forever. Line A straight course that has actually no thickness and extends forever. Point A place that has actually no size. Coplanar Points the lie in the same plane. Endpoint A suggest at an end of a segment or the starting point the a ray. Ray A part of a line that starts in ~ an endpoint and also extends forever in one direction. Postulate A statement that is accepted as true without proof, additionally called an axiom. Vertex The usual endpoint of the political parties of an angle. Opposite rays Two beam that have actually a common endpoint and form a line. Segment A part of a heat consisting of 2 endpoints and all points in between them. Distance The absolute value of the distinction of the coordinates of 2 points. Construction A method of creating a number that is taken into consideration to it is in mathematically precise. Between Given three points A, B, and also C, B is in between A and C if and also only if all 3 of the point out lie ~ above the same line, and abdominal + BC = AC. Coordinate plane A aircraft that is split into 4 regions by a horizontal line referred to as the x-axis and a vertical line dubbed the y-axis. Coordinate A number used to determine the location of a point. Congruent segments Two segment that have the same length. Degree A unit of angle measure. Midpoint The suggest that divides a segment right into two congruent segments. Bisect To divide into two congruent parts. Angle A figure formed by two rays v a common endpoint. Measure The use of units to discover a dimension or quantity. Segment bisector A line, ray, or segment that divides a segment into two congruent segments. Vertical angles The nonadjacent angles developed by 2 intersecting lines. Straight angle An angle formed by two opposite rays that actions 180°. Acute angle An angle the measures higher than 0° and less than 90°. Right angle An edge that actions 90°. Interior of one angle The set of all points in between the political parties of one angle. Obtuse angle An angle that measures higher than 90° and less 보다 180°. Exterior of one angle The set of all points outside an angle. Adjacent angles Two angle in the same airplane with a common vertex and also a usual side, however no typical interior points. Complementary angles Two angles whose measures have a amount of 90°. Supplementary angles Two angles 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 adjacent angles who noncommon sides space opposite rays. Congruent angles Angles that have actually the very same measure. Image A shape that outcomes from a transformation of a figure. Preimage The original figure in a transformation. Reflection A revolution across a line. Transformation A change in the position, size, or form of a figure. Rotation A revolution about a suggest P, such that each suggest and its photo are the exact same distance native P. Translation A transformation in which all the clues of a number move the same distance in the very same direction. leg One the the two sides the the right triangle that kind the best angle. Area The number of nonoverlapping unit squares of a given size that will exactly cover the interior of a plane figure. Hypotenuse The side opposite the appropriate angle in a right triangle. Length The distance in between the two endpoints the a segment. base Any next of a triangle. Height Asegment from a vertex that creates a best angle through a heat containing the base. Radius A segment who endpoints space the center of a circle and a point on the circle, or the distance from the facility of a circle to any point on the circle. Perimeter The sum of the next lengths the a closed airplane figure. pi The proportion of the circumference of a circle come its diameter, denoted through the Greek letter π. Circumference The distance about the circle.See more: How Is Symbolism In The Lady Or The Tiger ?
