If A is the area and 2s is the sum of the sides of a triangle, then

If A is the area and 2s the sum of three sides of a triangle, then

If A is the area and 2s the sum of the sides of a triangle,then

If Delta denotes area of triangle and P denotes the sum of the 3 sides of triangle then

p_1,p_2,p_3 are the altitudes of a triangle ABC drawn from the vertices A,B and C respictively . If Delta is the area of the triangle and 2s is the sum of its sides, a,b and c then 1/(p_1)+1/(p_2)-1/(p_3)=

Let one of the sides of a triangle be 17 cm and the sum of all the sides of the triangle be 40 cm. If the sum of two adjacent sides is 35 cm, then the area (in sq. cms) of the triangle is

Using vectors: Prove that if a,b,care the lengths of three sides of a triangle then its area Delta is given by Delta= sqrt(s(s-a)(s-b)(s-c)) where 2s=a+b+c

Using vectors: Prove that if a,b,care the lengths of three sides of a triangle then its area Delta is given by Delta=sqrt(s(s-a)(s-b)(s-c)) where 2s=a+b+c

Equilateral triangle are drawn on the three sides of a right angled Triangle. Show that the area of the Triangle on the hypotenuse is equal to the sum of the areas of triangle on the other two sides.

Equilateral triangles are drawn on the sides of a right triangle. Show that the area of the triangle on the hypotenuse is equal to the sum of the areas of triangles on the other two sides.
