Law of cosines
Yes, it can. And if you do the math, some basic trigonometry, you can calculate the angles in the triangle.
Sides and Angles in a TriangleBy definition, a triangle has three sides. Since the number of sides and angles is equal, it would also have three angles.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
The perimeter of a triangle is simply the sum of the lengths of its three sides. Knowing that it is right angles (or not) is rarely of help.
It's probably a triangle. A triangle has three sides and three angles.
There are many formulae for triangles: Some formulae will calculate sides given angles or conversely. Some will calculate the area. It is not possible to say how you would use a formula without knowing what it is for!
Yes, it can. And if you do the math, some basic trigonometry, you can calculate the angles in the triangle.
A triangle with no equal sides or angles will always be classified as 'scalene'.

The ratio can be used to calculate additional information about the sides or angles of a triangle.
Sides and Angles in a TriangleBy definition, a triangle has three sides. Since the number of sides and angles is equal, it would also have three angles.
You use Lami's theorem wen you triangle of forces to calculate the sides of the triangle or the angles opposite to a side.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
The perimeter of a triangle is simply the sum of the lengths of its three sides. Knowing that it is right angles (or not) is rarely of help.
A triangle has 3 angles and 3 sides, which is why it is called a TRIangle.
Yes a triangle consists of three sides and three angles.
That is the definition of a triangle. If it did not have three sides it would not be a triangle. If it did not have three angles, it would not be a triangle.
