Question

ABC is a right triangle right angled at 'C'. If BC-a, CA,
AB-c and 'p' be the length of perpendicular from 'e' to
AB', then
A)
B)
b
D) -
B​

Answer 1

Answer:

1.Area is 1/2 base * height . So for the same triangle area can be 1/2*b*a and can be 1/2*p*c. Hence cp = ab

2 . From above p2 = a2b2/c2

1/p2 = c2/ a2b2

but for right triangle c2 = a2 +b2

Hence 1/p2 = (a2+b2)/ a2b2

Hence 1/p2 = 1/a2+1/b2

Step-by-step explanation:

answer is option A.
