Ex 4.1, 6 Consider the following figure of line (ππ) β‘. Say whether following statements are true or false in context of the given figure. (a) Q, M, O, N, P are points on the line (ππ) β‘ True Here line (ππ) β‘ is the full line. So, points Q, M, O, N, P lie on it. Ex 4.1, 6 Consider the following figure of line (ππ) β‘. Say whether following statements are true or false in context of the given figure. (b) M, O, N are points on a line segment (ππ) Μ. True Here, line segment (ππ) Μ is from point M to point N. So, M, O, N lie on it. Ex 4.1, 6 Consider the following figure of line (ππ) β‘ . Say whether following statements are true or false in context of the given figure. (c) M and N are end points of line segment (ππ) Μ.True In line segment (ππ) Μ, M & N are the end-points. Ex 4.1, 6 Consider the following figure of line (ππ) β‘ . Say whether following statements are true or false in context of the given figure. (d) O and N are end points of line segment (ππ) Μ False In line segment (ππ) Μ, O and P are the end-points. Ex 4.1, 6 Consider the following figure of line (ππ) β‘ . Say whether following statements are true or false in context of the given figure. (e) M is one of the end points of line segment (ππ) Μ . False In line segment (ππ) Μ, Q and O are the end-points. Ex 4.1, 6 Consider the following figure of line (ππ) β‘ . Say whether following statements are true or false in context of the given figure. (f) M is point on ray (ππ) β False On ray (ππ) β, point O is fixed. So, M is not a point on it. Ex 4.1, 6 Consider the following figure of line (ππ) β‘. Say whether following statements are true or false in context of the given figure. (g) Ray (ππ) β is different from ray (ππ) β True Ray (ππ) β starts from point O Whereas Ray (ππ) β starts from point Q Ex 4.1, 6 Consider the following figure of line (ππ) β‘ . Say whether following statements are true or false in context of the given figure. (h) Ray (ππ) β is same as ray (ππ) β. . False Ray (ππ) β and (ππ) β are in opposite directions Ex 4.1, 6 Consider the following figure of line (ππ) β‘ . Say whether following statements are true or false in context of the given figure. (i) Ray (ππ) β is not opposite to ray (ππ) β False Ray (ππ) β and (ππ) β are in opposite directions False Ray (ππ) β and (ππ) β are in opposite directions False O is an initial point in ray (ππ) β Ex 4.1, 6 Consider the following figure of line (ππ) β‘ Say whether following statements are true or false in context of the given figure. (k) N is the initial point of (ππ) β and (ππ) β . Ex 4.1, 6 Consider the following figure of line (ππ) β‘ Say whether following statements are true or false in context of the given figure. (k) N is the initial point of (ππ) β and (ππ) β . Ex 4.1, 6 Consider the following figure of line (ππ) β‘ Say whether following statements are true or false in context of the given figure. (k) N is the initial point of (ππ) β and (ππ) β . True N is the initial point in ray (ππ) β and N is the initial point in ray (ππ) β Ex 4.1, 6 Consider the following figure of line (ππ) β‘ Say whether following statements are true or false in context of the given figure. (k) N is the initial point of (ππ) β and (ππ) β . True N is the initial point in ray (ππ) β and N is the initial point in ray (ππ) β
