Yes normally, a scalene triangle is an example.
The study is called trigonometry.

3 inches, an equilateral triangle has equal side lengths and angle measures
Too broad of a question... What measure are you talking about? angles? side lengths?
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
Yes normally, a scalene triangle is an example.
The study is called trigonometry.
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.

By using trigonometry that is applicable to a right angle triangle.
Too broad of a question... What measure are you talking about? angles? side lengths?
Relationship between the lengths and the measures of angles are related to theorems like the opposite side of the largest angle is the largest side two equal angles oppositee sides are also equal
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
