  • Question 3
    1 / -0

    Directions For Questions

    The steps for constructing an $$\angle ABC$$ of measure $$120^\circ$$ are given below in jumbled order:
    1. From the point $$E$$, mark a point $$F$$ on the same arc with the same radius.
    2. Place the pointed end of the compass on $$B$$ and draw a semi-circular arc with arbitrary radius and name its intersection with ray $$BC$$ as $$D$$.
    3. Draw a ray $$BC$$.
    4. From point $$D$$, mark a point $$E$$ on the arc with the same radius.
    5. Join $$B-F$$ and extend it to obtain ray $$BA$$

  • Question 6
    1 / -0

    Which of the following steps is INCORRECT while constructing an angle of $$60^o$$?
    Step-1: Draw a line EF and mark a point O on it.
    Step-2: Place the pointer of the compass at O and draw an arc of convenient radius which cuts the line EF at point P.
    Step-3 : With the pointer at A (as center) now draw an arc that passes through O.
    Step-4: Let the two arcs intersect at Q. Join OQ. We get $$\angle$$ QOP whose measure is $$60^o$$

  • Question 7
    1 / -0

    Construct a triangle ABC, given: BC = 7 cm, AB -AC =1 cm and $$\angle ABC =45^{\circ}$$. Measure the lengths of AB and AC.

  • Question 8

  • Question 9
    1 / -0

    Rearrange the following steps of constructing a triangle when the base angle say $$\angle B \,\, and \,\, \angle C$$ and its perimeter $$BC + CA + AB$$ is given:


    $$1.$$ Draw perpendicular bisectors $$PQ$$ of $$AX$$ and $$RS$$ of $$AY$$.
    $$2.$$ Draw a line segment, say $$XY$$ equal to $$BC + CA +AB$$.
    $$3. $$ Let $$PQ$$ intersect $$XY$$ at $$B$$ and $$RS$$ intersect $$XY$$ at $$C$$. Join $$A-B$$ and $$A-C$$.
    $$4.$$ Make $$\angle LXY$$ equal to $$\angle B$$ and $$\angle MYX$$ equal to $$\angle C$$.
    $$5.$$ Bisect $$\angle LXY$$ and $$\angle MYX$$. Let these bisectors intersect at a point $$A$$.
