How do you find the perimeter of a scalene triangle

-- 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.

True or False a right triangle cannot have three congruent sides

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.

True are false A triangle with sides lengths 40 75 and 84 are a right triangle

False.

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

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

In isosceles triangle WXY the interior angle W measures 100 degree. What is the measure of all three interior angles of triangle WXY

100 degree, 40 degree and 40 degree.

What is the length of BC in this triangle angle BAC equals 40 degrees and angle ABC equals 50 degrees and angle BCA equals 90 degrees .

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

Is it true or false that the legs are the sides that form the right angle in a right triangle

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

What is the length of in the right triangle below with legs of 18 and 80

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