Therefore, by Pythagoras theorem
XY = YZ + XZ⇒ 200x = 10000 + 3600
⇒ 200x = 13600
⇒ x = 13600/200
Therefore, distance between X and Y = 68 meters.
Therefore, length of each side is 8 cm.
Using the formula solve more word problems on Pythagorean Theorem.
3. Find the perimeter of a rectangle whose length is 150 m and the diagonal is 170 m.
In a rectangle, each angle measures 90°.
Therefore PSR is right angled at S
Using Pythagoras theorem, we get
⇒ PS = √6400
Therefore perimeter of the rectangle PQRS = 2 (length + width)
= 2 (150 + 80) m
= 2 (230) m
= 460 m
4. A ladder 13 m long is placed on the ground in such a way that it touches the top of a vertical wall 12 m high. Find the distance of the foot of the ladder from the bottom of the wall.
Let the required distance be x meters. Here, the ladder, the wall and the ground from a right-angled triangle. The ladder is the hypotenuse of that triangle.
According to Pythagorean Theorem,
Therefore, distance of the foot of the ladder from the bottom of the wall = 5 meters.
5. The height of two building is 34 m and 29 m respectively. If the distance between the two building is 12 m, find the distance between their tops.
The vertical buildings AB and CD are 34 m and 29 m respectively.
Draw DE ┴ AB
Then AE = AB – EB but EB = BC
Therefore AE = 34 m - 29 m = 5 m
Now, AED is right angled triangle and right angled at E.
⇒ AD = √169
Therefore the distance between their tops = 13 m.
The examples will help us to solve various types of word problems on Pythagorean Theorem.

Long-form conversations about teaching and learning with craig barton.
Interesting teaching ideas for introducing and revising pythagoras’ theorem and trigonometry.
Pythagoras’ theorem and trigonometry are two of those classic topics that pupils revisit year-on-year. This is partly because these topics come in many forms and interesting contexts, from basic Pythagoras and Soh-Cah-Toa, to graphs of trigonometric functions and calculus.
With the increased emphasis on ratio in the new GCSE specification, trigonometry is likely to start appearing in non-calculator papers as well. As such, it is more important than ever for students to get to grips with this crucial and fascinating area of mathematics.
Fortunately, TES Maths is here to help!
Below is a selection of 15 top Pythagoras and trigonometry resources, all uploaded by the talented members of the TES Maths community. Why not use them to give you some new ideas for teaching these topics across all year groups?

Hardly unique! But thanks for sharing. Your website is a really useful collection of resources.
Good point. That was the TES editor’s choice of title. I have changed to “interesting”!

Great post, some lovely questions and resources here I've not seen before. On the subject of triples, you may find this interesting: http://wp.me/p2z9Lp-bP And my very first ever (albeit not great) blog post was about Pythagoras in 3d! http://wp.me/p2z9Lp-9
Thanks Cav. Aah, your first post from 2012! I bet that feels like a long time ago. Love your triples post, I'll definitely use that method for finding triples. Also the proof by induction for FP1, great stuff.
Here’s a lesson I did when I visited a teacher with a year 8 class in a middle school in the summer term. She asked me if I could do a lesson which tied in some assorted revision and practice while leading the way towards Pythagoras – without spoiling the fun for their teachers in secondary school. Phew! I asked for five minutes to think about it and this is what we did. 1…..I asked the children to construct a rectangle as perfect as they could make it. (Lots of revision of basic 2-D shapes and their properties, vocabulary, and of course accurate use of instruments.) 2…..I then asked them to draw a diagonal of their triangle and rub out one of the two triangles. 3…..I asked them to construct an equilateral triangle on each side of their triangle and to find the area of each of the three triangles. (So there was lots more practice in constructing triangles and using equipment, not to mention finding an assortment of methods to find the areas.) 4…..Finally, I asked them to post their three answers on the board and see what they could observe. I was pretty pleased that I'd managed to come up with the whole lesson quickly from scratch. The word Pythagoras was never mentioned, but I rather hoped the lesson would have to come mind when they met one of the standard diagrams in a few months’ time. Of course, constructing semi-circles on the sides would have worked just as well, but I thought there’d be more mileage in using equilateral triangles.
Thanks for sharing this lesson Alan, it's fantastic. I love the use of accurate constructions, a skill that's always worth practising. I'm certainly going to borrow these ideas.

Lovely, thank you!
Hi Jo, Just popping by for some inspiration! So many great ideas for my year 9s! A great activity I've done for Pythagoras is giving each half of the class a rope with 13 knots in at equal distances and then ask them to make me a right angled triangle. It works as a great little race for students to start problem solving. Dan
Thanks Dan, fantastic idea!
I'm not maths teacher (or a physics teacher) but a former engineer turned trade union official. I still love maths and physics though and during my attempt to get a decent understanding of special relativity I came across this very simple way of understanding special relativity and time dilatation using only Pythagoras. There is, of course, more complex maths involved in relativity, but this use of only Pythagoras is brilliant and could be used with older students or 6th formers to get a conceptual understanding of an important physics concept. I wish someone had shown this to me when I was at school as I may have studied physics instead of going to Uni to chemistry and dropping out. Is worth checking out http://www.emc2-explained.info/The-Light-Clock/#.VgBs6ZcYNOI
Great post and ideas, thanks. Been inspired to post a link to an interactive Pythagoras tool of our own: http://www.mathelize.co.uk/pt.html
