**To construct:** An isosceles right angled triangle ABC where m∠C = 90**° **, AC = BC = 6 cm.

**Steps of construction:**

(a) Draw a line segment AC = 6 cm.

(b) At point C, draw XC ⊥ CA.

(c) Taking C as centre and radius 6 cm, draw an arc.

(d) This arc cuts CX at point B.

(e) Join BA.

It is the required isosceles right angled triangle ABC.
