Question

Constract a triangle AB=6cm ,angle CAB=45° ,angle CBA=60°

Answer 1

Step-by-step explanation:

*Draw a line segment AB of 6cm.

*With the centre 'A' draw a semicircle of any measurement.

*With the same measurement ,and centre as A' cut the semicircle by drawing an arc.

*Draw a line where the arc intersects, hence it measures 60 degree.

*Again with the centre A' draw an arc.

*With the centre of 60 degree cut that arc.

*Draw a line where the arc intersects.

*It measures 30 degree.

*With the centre of 60 degree draw an arc between 60 degree and 30 degree .

* Repeat the same, take 30 degree line as center and cut the arc . draw a line over it .

*It exactly measures 45 degree.

*Now with the centre as B draw the semicircle , again with center as b' cut the semicircle , construct a line over the intersection.

*Join A and B lines it gives angle C
