How do you find the longest side of a triangle without angles?

The hypotenuse is the longest side of a right triangle, and is located opposite the right angle which is the angle that measures 90 degrees. So, if you know the lengths of two sides, all you have to do is square the two lengths, add the result, then take the square root of the sum to get the length of the hypotenuse.

What is the formula for finding the longest side of a triangle?

Given two right triangle legs

Use the Pythagorean theorem to calculate the hypotenuse from the right triangle sides. Take a square root of sum of squares: c = √(a² + b²)

How do you find the angle of a triangle without angles?

What is the formula to find the unknown side of a triangle?

The Pythagorean theorem states that a² + b² = c² in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two.

How do you find unknown sides of a triangle?

How To Calculate The Missing Side Length of a Triangle

What is the longest side in a ∆?

The hypotenuse is always the longest side in a right triangle because it is opposite of the largest angle, the ninety degree angle.

How do you find the side of a triangle given two sides and no angles?

How do you find the third side of a triangle given two sides and no angles? The simple answer is you don't, because you can't. You need at least one other piece of information about the triangle.

What is the rule for side lengths of a triangle?

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

How do you find the 3rd length of a side in a triangle?

Different Ways to Find the Third Side of a Triangle

For a right triangle, use the Pythagorean Theorem. For an isosceles triangle, use the area formula for an isosceles. If you know some of the angles and other side lengths, use the law of cosines or the law of sines.

Can you solve for the unknown side in any triangle if you know the lengths of the other two sides by using the Pythagorean Theorem?

You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle's other two sides, called the legs. Put another way, if you know the lengths of a and b, you can find c.

How do you find the third side of a triangle with only 2 sides?

Finding Third Side of a Triangle given Two Sides

According to Pythagoras Theorem, the sum of squares of two sides is equal to the square of the third side.

Is the longest side always the hypotenuse?

The hypotenuse side of a right triangle is always across from the 90 degree angle (the little box). It is always the longest side of the triangle. The opposite and adjacent sides of a right triangle are the legs of the triangle and they form the 90 degree angle.

Is the longest side of a triangle always C?

C is the hypotenuse, which is the side opposite the right angle, and it's always the longest side.

What is the order of sides of △ DEF from shortest to longest?

The correct answer is: In △ABC, Sides shortest to longest are FD, DE, EF.

How do you find angles in a triangle?

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.

What is the value of the missing angle?

To find the missing angle, subtract the given angle from 180°. The result is the missing angle.

Do angles in a triangle add up to 360?

The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well. Half of 360° is 180°.
