You use the Pythagoras Theorem if it is a right-angled triangle. a squared + b squared = h (longest side, diagonal) squared, then square root h to find the longest side.
if it is not a right angled triangle, then use the Sine or Cosine rule.
Sine rule for: two angles and any one side or two sides and an angle that is not in between the sides.
Cosine rule for: all three sides (but then you do not need to find a missing side) or two sides and an angle that is in between.

What is the formula for finding a missing side on a congruent triangle?
It is the same length as the corresponding side on the other triangle.
Can Pythagorean Theorem can be used on any triangle to determine the length of a missing side?
yes
How do you find a missing length of a triangle?
It all depends on what information you DO have. If all you have is two lengths, then all you can say is that the missing side is greater than the difference between the two and less than the sum of the two.
How do you find the missing length of a triangle using Pythagoras?
The length of side A squared plus the length of side B sqaured equals the missing side of the triangle squared. So i.e. if side A is 4 and side B is 3 then 4x4 which is 16 plus 3x3 which is 9 equals 25 and the square root of 25 equals 5. So in conclusion the missing side equals 5.
How do you find the measures of a right triangle if the length and width are given?
The answer will depend on whether the length is the hypotenuse or one of the legs of the triangle.
What are the uses for his therom?
To find the missing length of a triangle
How do you find the missing measurements of a triangle if you only know one side?
they are all the same length
How can you find the length of the missing side of a triangle using square root?
You use the pythagorean theorem.
What does Pythagoras famous theroem involve?
It involves a right triangle. If a length is missing in a right triangle, you can find it out by using the other two lengths.
Find the missing length for a right triangle where the short side is 9 cm and the hypotenuse is 30cm?
The length of the other side is: 28.6 cm
What do you do in trigonometry?
usually its used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. any way you can use sine, cosine, and tangent, to fine the missing angle or length
Find missing measure in the triangle 63 65 x?
The third side can be of any length in the interval (2, 128) units of length.
How do you find the length to a missing side of a right triangle?
Pythagorean Theorem: a2 + b2= c2 where c is the hypotenuse of a right triangle. Hypotenuse is the side of a right triangle opposite to the right angle.
What is one way to find the missing side length?
One way to find a missing side length of a triangle is to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²). If you know the lengths of two sides, you can rearrange the formula to solve for the missing side. For example, if you have the lengths of the two legs (a and b), you can find the hypotenuse (c) by calculating c = √(a² + b²).
How do you use sine in math?
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
What is the formula for finding a missing side on a congruent triangle?
It is the same length as the corresponding side on the other triangle.
How do you find the missing measure of an acute triangle?
It depends on what measure is missing.
