Ncert-maths-Introduction to Euclids Geometry -Set A Welcome to your Ncert-maths-Introduction to Euclids Geometry -Set A 1. It is known that if x = 2z and y = 2z, then x = y. Then Euclid’s axiom that illustrates this statement is seventh axiom fourth axiom second axiom sixth axiom None 2. The line segment with one end point at the centre and the other at any point on the circle is called __________. diameter None of these radius chord None 3. It is known that x+y=10, then x+y+z=10+z. The Euclid's axiom that illustrates this statement is Fourth axiom First axiom Third axiom Second axiom None 4. Two salesmen make equal sales during the month of August. In September, each salesman doubles his/her sale of the month of August. Compare their sales in September. Equal sales in September Unequal sales in September None of the above Ambiguous None 5. Which of the following is NOT a Euclid's postulate? There is a unique line that passes through two given points Through a point not on a given line, exactly one parallel line may be drawn to the given line We can describe a circle with any center and radius All right angles are equal to one another None 6. If C lies between A and B and AB = 10cm, AC = 3cm, then BC²= 9 cm² 7 cm² 49 cm² 13 cm² None 7. If AB, AC, AD and AE are parallel to a line ‘q’, then the points A, B, C, D and E are Collinear Intersecting None of these Non-collinear None 8. It is known that if x+y=10 then x+y+z=10+z. The Euclid's axiom that illustrates this statement is: Second Axiom Third Axiom First Axiom Fourth Axiom None 9. If C is the mid-point of the line segment AB and L is the mid-point of AC, then AL = 1/3 AB AL = 1/4 AB AL = 3/4 AB AL = 1/2 AB None 10. Which of the following is Euclid's first postulate? All right angles are equal to one another. The whole is greater then the part. A straight line segment can be drawn joining any two points. A circle can be drawn with any centre and any radius. None 11. If point P lies on AB, then AB is always greater than AP. This concept is on which of the following Euclid's Axioms. First Axiom Fifth Axiom Second Axiom Third Axoim None 12. The number of line segments determined by three collinear points is 2 4 1 3 None 13. A statement accepted as true as the basis for argument or inference, is Corollary Conjecture Axioms Theorem 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? 6 1 4 8 None 15. 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 inconsistent Only (i) & (ii) are consistent Only (iii) is consistent consistent None 16. Two distinct ________ lines cannot be parallel to the same line. Non-intersecting Intersecting Parallel None of these None 17. Euclid stated that all right angles are equal to one another in the form of a/an .......... Proof Postulate Axiom Defination None 18. Which one of the following statements is false ? Two circles are equal when their radii are equal A terminated line can be produced indefinitely on both the sides. A figure formed by line segments is called a rectilinear figure. Only one line can pass through a single point None 19. 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. Either Inconsistent Consistent Neither None 20. Which Euclid's postulate led to the discovery of several other geometries while attempting to prove it using other postulates and axioms Second Postulate Third Postulate Fifth Postulate First Postulate None Time's up Please Share This Share this content Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Leave a Reply Cancel replyCommentEnter your name or username to commentEnter your email address to commentEnter your website URL (optional) Save my name, email, and website in this browser for the next time I comment.
