To create a triangle, the sum of the two shorter sides must be greater than the third side.
If the longest side is one of the two given sides, then the missing side must be greater than the difference between the two shorter sides.
If the missing side is the longest side then the missing side must be less than the sum of the two shorter sides.
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
By using trigonometry or Pythagoras' theorem depending on what type of triangle it is.
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
Proportions would be the best way; given the sides of the triangle, use ratios to find the corresponding side on the congruent triangle. For example: if three sides are given, 3, 4, and 5, and you had to solve a triangle with lengths 9, 12, and x, this is how you would do it. Given the triangles are congruent, 4/5 = 12/x 4x = 60 x = 15
take the number and divide it by 180 if it's a triangle
to find the range of values of triangle. Add the value of the sides of the given sides...is it?
Square the two smaller sides and add them together. Take the square root of the answer. If that is the same as the third side then you have a right angled triangle and if not, then you have not.
The lengths of two sides are not enough to determine the perimeter of a triangle: Either the third side or else the angle between the two given sides is also needed. If two of the sides are 10m and 25m, then the third side can be anything between 15m and 35m, and the perimeter can be anything between 45m and 70m.
You cannot. If the lengths of the two sides are a and b where a>=b, then all that can be said about the third side, c, is that (a - b) < c < (a + b)
By using sides we get area of triangle and then using (1/2)heightxbase we get height.
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
We use Pythagoras property to find the length of the third side, when two sides of a right-angled triangle are given by the following formula: In a right triangle, Square of hypotenuse = sum of squares of other two sides.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.

If two sides are given and you need to know the length of the third side use the Pythagrean Theorem formula. Then you find the square root. c² = a² + b²* * * * *That is useful only if the triangle is a right angled triangle. Most are not. The correct answer depends on what information you do have.

The cosine rule which is: a2 = b2+c2-2*b*c*cosine A This is used to find the third side of a triangle when the two other sides are known along with the angle between them. Used when the triangle is not a right angle.
