Unequal sales in September None of the above Ambiguous Equal sales in September None 5. It is known that x+y=10, then x+y+z=10+z. The Euclid's axiom that illustrates this statement is Fourth axiom Second axiom Third axiom First axiom None 6. A statement accepted as true as the basis for argument or inference, is Conjecture Theorem Axioms Corollary None 7. Which one of the following statements is false ? A terminated line can be produced indefinitely on both the sides. A figure formed by line segments is called a rectilinear figure. Two circles are equal when their radii are equal Only one line can pass through a single point None 8. If C is the mid-point of the line segment AB and L is the mid-point of AC, then AL = 3/4 AB AL = 1/2 AB AL = 1/4 AB AL = 1/3 AB None 9. Read the following axioms:(i) Things which are equal to the same thing are equal to one another.(ii) If equals are added to equals, the wholes are equal.(iii) Things which are double of the same thing are equal to one another.Check whether the given system of axioms is consistent or inconsistent. Consistent Neither Inconsistent Either None 10. Read the following axioms:(i) Things which are equal to the same thing are equal to one another.(ii) If equals are added to equals, the wholes are equal.(iii) Things which are double of the same thing are equal to one another.Check whether the given system of axioms is consistent or inconsistent Only (iii) is consistent inconsistent consistent Only (i) & (ii) are consistent None 11. If AB, AC, AD and AE are parallel to a line ‘q’, then the points A, B, C, D and E are Intersecting None of these Non-collinear Collinear None 12. Which of the following is Euclid's first postulate? All right angles are equal to one another. A straight line segment can be drawn joining any two points. The whole is greater then the part. A circle can be drawn with any centre and any radius. None 13. If C lies between A and B and AB = 10cm, AC = 3cm, then BC²= 49 cm² 7 cm² 13 cm² 9 cm² None 14. Given four distinct points in a plane. How many line segments can be drawn using them when no three of them are collinear? 4 8 1 6 None 15. If point P lies on AB, then AB is always greater than AP. This concept is on which of the following Euclid's Axioms. Fifth Axiom Second Axiom First Axiom Third Axoim None 16. Which Euclid's postulate led to the discovery of several other geometries while attempting to prove it using other postulates and axioms First Postulate Fifth Postulate Second Postulate Third Postulate None 17. Euclid stated that all right angles are equal to one another in the form of a/an .......... Axiom Proof Defination Postulate None 18. The number of line segments determined by three collinear points is 1 4 3 2 None 19. It is known that if x+y=10 then x+y+z=10+z.
