Let a, β, y be the three interior angles of any triangle, and try to prove that cos(a+β+y) = -1.
7nadin3 [17]

Given:

\alpha, \beta, \gamma are three interior angles of any triangle.

To prove:

\cos (\alpha+\beta+\gamma)=-1

Solution:

According to the angle sum property of a triangle, the sum of all three interior angle of a triangle is always 180 degrees.

It is given that, \alpha, \beta, \gamma are three interior angles of any triangle.

Using the angle sum property of triangles, we get

\alpha+\beta+\gamma =180^\circ              ...(i)

We need to prove,

\cos (\alpha+\beta+\gamma)=-1

Taking LHS, we get

LHS=\cos (\alpha+\beta+\gamma)

LHS=\cos (180^\circ)                [Using (i)]

LHS=-1

LHS=RHS

Hence proved.
