Question

Draw a line AB of measure 60 degree such that AB= 4.5 cm and BC= 5 cm. through C draw a line parallel to AB and through B draw a line parallel to AC, intersecting each other at D. measure BD and CD.​

Answer 1

Answer:

Draw a line segments BC= 5\ cmBC=5 cm using scale.

At point BB , draw an angle 60\ degree60 degree using protector like \angle ABC=60\ degree∠ABC=60 degree .

Through point CC , draw a perpendicular line on ABAB which meet line ABAB at EE like CE\perp ABCE⊥AB

At point CC , draw a perpendicular line with CECE which is parallel with ABAB

Again Through point BB , draw a perpendicular line on ACAC which meet line ACAC at FF like BF\perp ACBF⊥AC

At point BB , draw a perpendicular line with BFBF which is parallel with ACAC

This two line meet at DD

In figure AB=CD=4.5\ cmAB=CD=4.5 cm and measure the length BDBD using where AC=BDAC=BD
