The medians of a right triangle that are drawn from the vertices of the acute angle are 5 and40. What is the length of the hypotenuse? Right Triangle: A triangle is a closed polygon formed by any three non-collinear points on ...
Note that the mass of D is twice the mass of A, so AP must be twice as long as PD. PD has length 2, so AP has length 4 and AD has length 6. Similarly, CP is twice PE and PE=1.5, so CP=3 and CE=4.5. Now note that triangle PED is a 3−4−5 right triangle wit...
