There is no rule for the perimeter of an acute triangle. You simply need to add the sides.
The answer depends on the information that you have: it could be the sine rule or the cosine rule.
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
If you know the lengths of the sides, you can use the cosine rule. If you have information about other aspects of the triangle, then other formulae will apply.
no it cannot represent as in angle triangle rule it doesnt prove that term
sorting rule means sort out according to size and kind
there are 3 angles in a triangle which is mathematically true if you check in the math rule book and rule determined by Andres Schavascapel
Pascal's rule for his triangle pattern is all the sides are ones
There is no rule for the perimeter of an acute triangle. You simply need to add the sides.
There is no single rule. It is a right angled isosceles triangle. Its long side (hypotenuse) is sqrt(2) times the short sides.
Pythagoras's' theorem or "got an want" on a right angled triangle but use sine rule on a non right angled triangle !! ..
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
small green triangle

Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)
The answer depends on the information that you have: it could be the sine rule or the cosine rule.
Go to the demo you wish to delete and press Triangle. You'll see the delete option appear along with other options for sorting, etc.
