From the Pythagorean Theorem: c^2 = a^2 + b^2. So,
c = √(a^2 + b^2) substitute the given values:
c = √(4^2 + 3^2)
c = √(16 + 9)
c = √25
c = 5 (since the length is always positive)
One of the Pythagorean triples is 3,4,5. So, if you know all the Pythagorean triples, you don't need to do the computations above.
The Pythagorean triple: A set of three positive integers a, b, and c such that a^2 + b^2 = c^2. Pythagorean triples that have greatest common divisor equal to 1 include the following: {3, 4, 5}, {5,12, 13}, {8, 15, 17}, {7, 24, 25}, and {20, 21, 29}.
It is impossible to get a triangle with the side lengths 14cm, 3cm and 8cm 14cm itself is larger than the sum of two other lengths (3cm + 8cm = 11cm).
what triangles measure 3cm 5cm and 3cmA triangle that has two legs that are equal is an isosceles triangle.
The area is 12cm2

To find the perimeter of something all you have to do is, MEASURE THE DISTANCE AROUND THE OBJECT, for example if you have a triangle and the left side is 8cm, the right side is 5cm, and the bottom is 3cm, add the three measurements, 8cm + 5cm + 3cm = 16cm
5 cm
5cm

For it to be a right angle triangle the 3rd side must be 5cm
yes it is. When you're dealing with the Pythagorean theory, a 3,4,5 triangle is a special triangle. For example, if a triangle has side lengths of 3cm and 4cm, then you automatically know that the other side length is 5cm. It also works if the side lengths are 5cm and 4cm or 5cm and 3cm.
There is no triangle with sides 14 cm, 3cm and 8cm. For a triangle to exist the sum of the two shorter sides must be longer than the remaining side. 3 cm + 8 cm = 11 cm < 14cm
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm

If both legs of a right triangle are the same, then it forms what is known as a "45-45-90 triangle". In this type of triangle, the hypotenuse is always √2 times more than the legs. So in this problem, with legs 3cm and 3cm, the hypotenuse is 3√2cm, or 4.243cm
In a right triangle, C2 = A2 + B2 That means that the square of the length of the longest side (called the "hypotenuse") is equal to the sum of the squares of the two shorter sides. So in order to find the length of the longest side, you square one side, then square the second side, add the two together, and take the square root of the sum. Now that you know that, you're fully equipped and perfectly capable of answering the question on your own.
