Theorem 7.7 : In any triangle, the side opposite to the larger (greater) angle is longer

Text Solution

AI Generated Solution

To prove that in any triangle, the side opposite to the larger angle is longer, we can follow these steps: ### Step 1: Consider Triangle ABC Let triangle ABC be given, where we know that angle C is greater than angle B (∠C > ∠B). ### Step 2: Assume the Opposite Assume for contradiction that the side opposite to angle C (which is side AB) is not longer than the side opposite to angle B (which is side AC). This means we assume that side AC is greater than or equal to side AB (AC ≥ AB). ...

When any two sides and one of the opposite acute angle are given, under certain additional conditions two triangles are possible. The case when two triangles are possible is called the ambiguous case. In fact when any two sides and the angle opposite to one of them are given either no triangle is posible or only one triangle is possible or two triangles are possible. In the ambiguous case, let a,b and angle A are given and c_(1), c_(2) are two values of the third side c. On the basis of above information, answer the following questions Two different triangles are possible when
