Question

Construct a triangle abc in which bc=12cm ,angle b=90degree ab+bc=18

Answer 1

Step-by-step explanation:

Given = ab+bc=18cm

bc=12cm

So, ab= 6cm (from above)

Now,

Draw a line bc of 12cm

Then keep the compass on b and draw 90°

We know that ab = 6cm

So take a scale and mark 6cm and name the point a

Join a and c

The required triangle is formed.
