5. ### 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...

8. ### 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 :(...
9. ### height of a traingle

Hi, i have a question where as it tells me that i need to find the area, i know to find the area of a traingle its half the base times the height, just i don't have the height and don't know how to find it inorder to find the area. the triangle is isoceles and has a 8cm base two sides are 5cm...
