A circle is inscribed in a right angled isosceles triangle. O is the centre of the circle which touches the triangle ABC at X, Y, Z. If AB = 7√2 cm, then the ratio of AZ : BX : CY -
Explanation:
If ACB is a right angled isosceles triangle and AB is hypotenuse with length 7*(2) length, then sides AC and BC = 7 cm Now, the circle inscribed is an incircle. Radius of in-circle = {7 + 7 - [7*(2)]}/2 = 7 - 722 Now, if center of circle is marked as O, then quadrilateral OZCY is a square. Hence, CY = CZ = 7 - 722 Hence, AZ = 7 - 7 - 722 = 722 Also, BX = BY and BY = BC - CY = 722 Hence, BX = 722
Hence, the given ratio becomes 1 : 1 : [(2) - 1]
