Question

Construct a triangle abc in which angle b=45 angle c=120 and ab+bc+ca=10.5 cm write steps of construction

Answer 1

Step-by-step explanation:

Draw a triangle with angle b = 45 degrees and angle c = 120 degrees.

Draw BC. (any length)

At B measure 45 degrees and draw a line.

At C measure 120 degrees and draw a line.

Both meet at point A.

Traingle ABC is formed.  with correct angles.

It's a scalene triangle.

Measure the sides. If the sum is not 10.5 units, then do following steps.

Draw any parallel line to BC. It still forms a triangle with above angular properties.

Measure the new triangle sides and check if it is 10.5.

Keep doing this until you get correct triangle.
