In triangle ( mathrm{ABC} ) if ( (A B)^{2}

Question

In triangle ( mathrm{ABC} ) if ( (A B)^{2}<(B C)^{2}+(A C)^{2} ) then ( angle C ) is

Accepted Answer

Step:1 ：( (A B)^{2}<(B C)^{2}+(A C)^{2} )Step:2 ：( cos{angle C} > 0 )Step:3 ：(0 < angle C < 90° )

Answer

Step: 1 ：( (A B)^{2}<(B C)^{2}+(A C)^{2} )Step: 2 ：( cos{angle C} > 0 )Step: 3 ：(0 < angle C < 90° )

In triangle \( \mathrm{ABC} \) if \( (A B)^{2}< (B C)^{2}+(A C)^{2} \) then \( \angle C \) is
