Answer 2

Construction of a triangle

Step-by-step explanation:

Given: In triangle ABC, base BC = 8cm, angle B = 45.

AB - AC = 3.5​ cm

Construction:

1. Draw the base BC = 8 cm.
2. At the point B make an angle XBC = 45°.
3. With B as center and radius as 3.5cm, cut an arc on the ray BX at D.
4. Join DC.
5. Draw the perpendicular bisector of DC. Let it be PQ.
6. Extend PQ such that it intersects ray BX at A.
7. Join AC.

ABC is the required triangle.
