1.

Construct a triangle ABC in which BC=8cm, ∠B=45 Degree and AB - AC = 3 . 5 cm​

Answer»

ong>Answer:

.Draw base BC of length 8cm

2.Now, LET's draw ∠B=45°

.Let the ray be BX

3.Open the COMPASS to length AB−AC=3.5cm.

Since AB−AC=3.5cm is POSITIVE.

So, BD will be above line BC

From point B as center, cut an ARC on ray BX.

Let the arc intersect BX at D

4.Join CD

5.Now, we will draw perpendicular bisector of CD

6.Mark point A where perpendicular bisector intersects BD

7.Join AC

Result:∴△ABC is the required triangle.
