It undergoes the concept of the Pythagorean theorem that is, the distance between the security camera and the place where the person is noted is well projected through the lens using the concept. As the main concept indicates if the cardboards being square can be made into a triangle easily by cutting diagonally then very easily the Pythagoras concept can be applied. Most woodworks are made on the strategy which makes it easier for designers to proceed.
It's a very amazing fact but people traveling in the sea use this technique to find the shortest distance and route to proceed to their concerned places. Usually, surveyors use this technique to find the steep mountainous region, knowing the horizontal region it would be easier for them to calculate the rest using the Pythagoras concept.
The fixed distance and the varying one can be looked through a telescope by the surveyor which makes the path easier. If you want to build more conceptual knowledge with the help of practical illustrations try Pythagoras Theorem Worksheets. Also, check out few more interesting articles related to Pythagoras Theorem for better understanding. Example 1: Consider a right-angled triangle. The measure of its hypotenuse is 16 units. One of the sides of the triangle is 8 units. Find the measure of the third side using the Pythagoras theorem formula?
Example 2: Julie wanted to wash her building window which is 12 feet off the ground. She has a ladder that is 13 feet long. How far should she place the base of the ladder away from the building? We can visualize this scenario as a right triangle. We need to find the base of the right triangle formed. Example 3: Kate, Jack, and Noah were having a party at Kate's house.
After the party gets over, both went back to their respective houses. Jack's house was 8 miles straight towards the east, from Kate's house. Noah's house was 6 miles straight south from Kate's house. How far away were their houses Jack's and Noah's?
We can visualize this scenario as a right-angled triangle. That means Jack and Noah are hypotenuses apart from each other. The converse of Pythagoras theorem is: If the sum of the squares of any two sides of a triangle is equal to the square to the third largest side, then it is said to be a right-angled triangle.
The Pythagoras theorem works only for right-angled triangles. When any two values are known, we can apply the Pythagoras theorem and calculate the other. The square of the hypotenuse of a right triangle is equal to the sum of the square of the other two sides.
The next step is to move one of the blue triangles vertically into the hypotenuse square. It fits exactly along the side of the hypotenuse square because the sides of a square are equal. The next step is to move the other blue triangle into the hypotenuse square. We are half way there! The next step is to slide the form of the original triangle to the left into the red region. The triangle cuts the red region into three pieces, two triangles and a small yellow square.
The original triangle fits exactly into this region because of two reasons; the vertical sides are identical, and the horizontal side of the red region is equal to the length of the red square plus the horizontal length of the red rectangle which we moved.
The horizontal length of the red region is:. The horizontal length of the red region is exactly the length of the horizontal side of the original triangle. The yellow square has dimensions b - a on each side. The next step is to move one of the red triangles into the hypotenuse square. Again it's a perfect fit. The next step is to move the final red triangle into the hypotenuse square. Now if we look at the grey square that remains in the hypotenuse square, we see that its dimensions are b - a ; the long side of the triangle minus the short side.
The final step is to move the yellow square into this hole. It's a perfect fit and we have used all the material from the original red and blue squares. The theorem states that: For any right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Here's an interactive Java program that let's you see that this area relationship is true: This page shows an interactive Java applet which demonstrates the Pythagorean Theorem.
Activities: Guided Tours Navigation.. Since the square of the length of the longest side is the sum of the squares of the other two sides, by the converse of the Pythagorean Theorem, the triangle is a right triangle. In a triangle with side lengths a , b , and c where c is the length of the longest side,. Check whether the triangle with the side lengths 5 , 7 , and 9 units is an acute, right, or obtuse triangle. Compare the square of the length of the longest side and the sum of squares of the other two sides.
Therefore, by the corollary to the converse of Pythagorean Theorem, the triangle is an obtuse triangle.
