    Find Perimeter of a Right Traingle w/ Hypotenuse & Area

    Hi everyone! I've been struggling with this problem recently, and don't really understand how I'm supposed to solve it: A hypotenuse of a right triangle has length 8. The area of the triangle is also 8 units squared. What is the perimeter of the triangle? Any help would be appreciated!

    Traingle from a set of points

    There are 10 points on a plane out of which 6 are collinear. How many triangles can be formed using these points as vertices. I have tried it in two methods, and i getting different answers, i am not sure what is wrong in my approach. first, 10c3 - 6c3 = 100 i.e , taking three points from...

    Existence of a traingle that can be cut to 2005 conruent trianlges..

    Prove that such a triangle exists that can be fully cut to 2005 congruent triangles... Well, this is wht I first did, I imagined an equilatoral triangle, joined the 3 mid points and obtained a fractel like the MHF symbol, but the problem is, the total no. of tiranlges is always a power of y4 :(...
