Answer :

We have been given two sides and one angle of right angled triangle ABC.

Steps of construction for this case would be:

1. Draw a line segment sufficiently long using a ruler.

2. Locate points A and B such that AB = 5 cm, on the previous drawn line segment using a ruler.

3. At B, construct a line segment BX, sufficiently large, such that ∠XBA = 90° using a compass; use protractor to measure the angle 90°.

4. With A as centre and radius 7 cm, draw a circle or a semicircle or an arc cutting the line segment BX at C.

5. Join AC.

Thus, ABC is the required triangle.
