Answer:
NO
Step-by-step explanation:
Note :
Consider a triangle with sides‘s length a , b and c
triangle inequalities state that we must have c - a < b < c + a
now , is the third side always the longest ?
the answer is NO: (let’s take a counter example )
in a triangle with 2 sides‘s length 3 , 4
the third side could measure 2
because 4-3 < 2 < 4+3
Answer:
tan(F)
Step-by-step explanation:
This is an isoceles triangle, both sides are the same so both the angles are the same as well. The sine and cosine of angles D and F are going to be the exact same because of the same sides. The only one that would be different would be the tangent of F or D.
