the rjoht
angle​

Answer 1

Answer:

We follow several steps in the construction:

1. Draw a ling segment which is sufficiently long using ruler.

2. Locate points A and B on it such that AB=5cm.

3. With A as centre and radius 4cm, draw an arc.

4. With B as centre and radius 4.3cm, draw another arc cutting the previous arc at C.

5. Join AC and BC

Then ABC is the required triangle.
