Question

construct triangle ABC BC = 7cm , angle B = 45° , AB+AC = 7.2​

Answer 1

Step 1 : Draw a line segment BC of length 7cm

Step 2 : Draw an angle of 45

o

from point B

Step 3 : From Ray AX cut off the line segment BD=1cm

Step 4 : Join C to D

Step 5 : Draw side bisector of DC

Step 6 : Extend side bisector of DC it intersect the Ray BX at point A

Step 7 : Join A to C, ABC is the required triangle.

On measuring, AB=6.1cm,AC=5.1cm
