Ex 5.1, 2Give a an interpretation for each of the adhering to terms. Are there various other terms that must be characterized first? What space they, and how can you define them?parallel lines Perpendicular linesLine SegmentRadius of circleSquareFor the preferred definition, we need the adhering to terms : point Line (c) airplane (d) angle (e) circle (f) Quadrilateral.First we define them, and also then the other definitionsPoint (b) heat (c) airplane (d) angle (e) one (f) quadrilateral.(a) Point: A little dot made by a spicy pencil top top a sheet file gives an idea about a point. A suggest has no dimension, it has actually only a position (b) Line: It must be straight & should expand infinitely in both directions. (c) Plane: The surface of a smooth wall or the surface of a paper of record is a plane. (d) Angle: space between 2 intersecting lines. (f) Circle: A one is the set of all those clues in a aircraft whose street from a fixed suggest remains constant. The fixed suggest is referred to as the center of the circle.(g) Quadrilateral: A closed figure made of four line segments is dubbed a quadrilateral.Ex 5.1, 2Give a definition for every of the complying with terms. Space there various other terms that must be defined first? What are they, and how can you specify them?Parallel linesTwo currently are stated to be parallel whenThey are not intersecting They are coplanar (in the exact same plane)In figure, the two lines L1 and L2 are parallel.Ex 5.1, 2Give a meaning for each of the complying with terms. Room there various other terms that need to be defined first? What room they, and also how might you specify them?(ii) Perpendicular linesTwo lines ab and CD lie the same aircraft are said to it is in perpendicular, if lock lie in the very same planeThey intersect to form a appropriate anglesssHere ab is perpendicular come CD .Ex 5.1, 2Give a definition for every of the complying with terms. Are there other terms that must be defined first? What room they, and how could you specify them?(iii) heat segmentLine segment : A heat segment is a part of line we truncate the heat by making two points.Here ab is a heat segment.Ex 5.1, 2Give a an interpretation for every of the complying with terms. Space there various other terms that need to be characterized first? What room they, and also how can you define them?(iv) Radius the a circleThe street from the center to a suggest on the circle is referred to as the radius that the circle. Below O is centre of circle & OP is the radius.Ex 5.1, 2Give a meaning for every of the adhering to terms.
