How Helmets Came To Be Used in Cricket
Nari Contractor was the Captain and an opening batsman for India in the 1960s. The Indian cricket team went on a tour to the West Indies in 1962. In a match against Barbados in Bridgetown, Nari Contractor was seriously injured and collapsed. In those days helmets were not worn. Contractor was hit on the head by a bouncer from Charlie Griffith. Contractor’s skull was fractured. The entire team was deeply concerned. The West Indies players were worried. Contractor was rushed to hospital. He was accompanied by Frank Worrell, the Captain of the West Indies Team. Blood was donated by the West Indies players. Thanks to the timely help, Contractor was saved. Nowadays helmets are routinely used against bowlers.
ABC is a triangle in which altitudes BE and CF to sides AC and AB are equal (see Fig). Show that
(i) ∆ ABE ≅ ∆ ACF
(ii) AB = AC, i.e., ABC is an isosceles triangle.

∆ABC is an isosceles triangle in which AB = AC. Side BA is produced to D such that AD = AB (see Fig. 7.34). Show that ∠ BCD is a right angle.
