-- Find the length of one side.

-- Find the length of another side.

-- Find the length of the remaining side.

-- Add the three numbers.

-- Their sum is the perimeter of the scalene triangle.

The Pythagorean Theorem states that in a right triangle with legs a and b and hypotenuse c, a2 + b2 = c2.

The converse of the Pythagorean theorem states that, if in a triangle with sides a, b, c,

a2 + b2 = c2

then the triangle is right and the angle opposite side c is a right angle.

That's true.

In a right triangle, the square of one side must be the sum of the squares of the other two sides.
So it's impossible for all three sides to be equal.

2892 = 289 x 289 = 83,521

False.

The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?

NO

The second one is shorter

Type your answer here... In a right triangle, the hypotenuse equals the sum of the squares of the legs.

Using Pythagoras' theorem the length of the hypotenuse is 39 units of measurement.

100 degree, 40 degree and 40 degree.

In order to find length BC the length of AC or length of the hypotenuse must be given

39

It is true and the longest side of a right angle triangle is its hypotenuse.

Using Pythagoras' theorem its hypotenuse will be 20

Using Pythagoras' theorem the hypotenuse of the right angle triangle works out as 15.

120

Since there is no triangle "below", all that can be said is that EF - if it is the third side of the triangle - is any length in the interval (24, 54).

The answer depends on the labels of the sides which are 19 and 12.

Use Pythagoras' theorem to find the 3rd side

Use Pythagoras' theorem to find the 3rd side

If 39 is the hypotenuse of the right triangle then by using Pythagoras' theorem the 3rd length is 36 units

Using Pythagoras' theorem for a right angle triangle its hypotenuse is 82 units in length
