Supercharge your learning.

Here we will learn about Pythagoras theorem, including how to find sides of a right-angled triangle and how to use Pythagoras theorem to check if a triangle has a right angle or not. Pythagoras theorem states that the square of the longest side of a right angled triangle called the hypotenuse is equal to the sum of the squares of the other two sides. Side c is known as the hypotenuse , which is the longest side of a right-angled triangle and is opposite the right angle. Side a and side b are known as the adjacent sides because they are adjacent next to the right angle. If we know any two sides of a right angled triangle , we can use Pythagoras theorem to work out the length of the third side.

Magic for Learning and Revision. Of course, it only applies to right-angled triangles, but is a very important theorem. It can also be used in reverse, to check if an angle is 90 o. Pythagoras was more than just a mathematician — he founded a school that studied philosophy and religion, and was head of the Secret Pythagorean Society. The inner circle of members were not allowed personal possessions, had to be vegetarian and follow strict rules. Members of the Society tried to keep it a secret, but a whistleblower revealed the secret, and the Society collapsed. All that because of a number! You've had your free 15 questions for today.

Example 2: finding the pythagoras theorem questions gcse of the hypotenuse finding the length of the longest side Find x and give your answer to 3 significant figures: Label the sides of the triangle. It is very important to label the hypotenuse the longest side correctly with c.

If we know any two sides of a right angled triangle , we can use Pythagoras theorem to work out the length of the third side. We can see that three squares have been drawn next to each of the sides of the triangle. We can see that when we add together the areas of the squares on the two shorter sides we get the area of the square on the longest side.

The hypotenuse is always the longest side of the triangle and can be found opposite the right angle. Calculate the distance between -4, -1 and 3, 4. First we plot the two points on a pair of axes, draw a line connecting them and then draw a triangle underneath making a note of the lengths of the sides:. Note: The length you are trying to calculate, when finding the length of a line between two points, will always be the hypotenuse. Find length BC. Give your answer to 1 decimal place.

By calculation, deduce whether triangle ABC is a right-angled triangle. Learning checklist You have now learned how to: Use Pythagoras theorem to find the length of the longest side of a right-angled triangle — its hypotenuse Use Pythagoras theorem to find the length of one of the shorter sides of a right-angled triangle. Write down the formula and apply the numbers. An isosceles triangle can be made into 2 right-angled triangles by putting in the line of symmetry.

Example 5: checking if a triangle has a right angle Is the triangle below a right-angled triangle? At the same time the Egyptians were using the theorem to help them with right angles when building structures. What is Pythagoras theorem? Pythagoras theorem video. Third side is 8 cm and is the longest so it is the hypotenuse. Question 4: LMN is a right-angled triangle.
