Question

2. Draw a
triangle ABC in which BC = 8 cm, ZB = 50° and ZA = 50°. Also bisect A
and ZC.​

Answer 1

Answer:

∵ Sum of angles of a triangle=180

∘

⟹∠BAC=180−(60+45)=75

∘

Now, to check the statement.

i)Draw a line segment XY=11cm.

ii)Make an angle equal to ∠B=60 from point X and mark L on this line.

iii)Make an angle equal to ∠C=45

∘

from point Y and mark M on this line.

iv)Bisect ∠LXYand∠MYX,let the bisectors meet at point A.

v)Make perpendicular bisector of AX,let it intersect XY at B.

vi)Make perpendicular bisector of AY,let it intersect XY at point C.

vii)Join AB & AC ,Then measure AB+BC+AC.

If that is equal to 11cm.

The statement is true and ABC is the required triangle.
