If in a `Delta ABC, /_ C=90^@,` then the maximum value of `sinA sinB` is

Statement 1 a+b+c=18(a,b,cgt0) , then the maximum value of abc is 216. Statement 2 Maximum value occurs when a=b=c .

In a right angle triangle ABC, right angle is at B ,If tan A=sqrt(3) , then find the value of (i) sin A cos C+ cos A sin C " "(ii) cos A cos C -sin A sin C

If Delta = |[1, 3costheta, 1], [sintheta, 1, 3costheta], [1, sintheta, 1]| , the maximum value of Delta is

If A(4,-6), B(3,-2) and C(5,2) are the vertices of Delta ABC , then verify the fact that a median of Delta ABC divides it into two triangles of equal areas.

In triangle ABC and triangle DEF, AB = DE, BC = EF and angleB = angleE . If the perimeter of triangle ABC is 20, then the perimeter of triangle DEF is ..........

In Delta ABC , AB = 20 cm, BC = 21 cm and the perimeter of Delta ABC = 70 cm. Find the area of Delta ABC using Heron's formula.

If A(2,2) , B(-4,-4) and C(5,-8) are the vertices of Delta ABC then the length of the median through C is . . . . . Units

If sinA=9/41 , find the values of cos A and tanA.

In triangle ABC internal angle bisector AI,BI and CI are produced to meet opposite sides in A',B',C' respectively. Prove that the maximum value of (AIxxBIxxCI)/(A A'xxBB'xxCC') is 8/27
