# Thread: [SOLVED] Dissecting squares to form other shapes

1. ## [SOLVED] Dissecting squares to form other shapes

With two straight cuts, dissect a square into three triangle such that they can be put together without overlapping so that they form an obtuse angle triangle.

I have no idea how to proceed.

Thanks for any help.

wat do u mean? 3 triangles then 3 obtuse angles? 3 triangles w/c one is an obtuse triangle?

there are 3 triangles one is an obtuse triangle..

No, you split the square into 3 pieces, then rearrange the pieces to form an obtuse angled triangle, where one angle is >90 and <180.

4. ahh, i got it. i think i need time to figure out. just one advice: try use a paper and cut it. i'll try do it.

5. First of all cut 1 out of square and place it as in figure
Next cut 2 out of 1 and place it
watch the right angles and the isoceles triangle 1 you will get it

6. Ahh.. Sorry

Yeah, I didn't really understand that explanation - I couldn't see the the 3 distinct pieces and how they formed one obtuse angled triangle.

7. -First of all draw a line parralel to base with height twice as that of side of square

-Now From the diagonal of square join the endpoint of the square to the parrallel line

- Join the basepoint to the point of intersection of parralel line with the new line

- Now you will be able to see the cut
