WebJan 23, 2024 · Assuming you meant a scale factor of 1:2 vice 1-2, then triangle A'B'C' is twice as big as triangle ABC (triangle ABC is the 1, triangle A'B'C' is the 2). That means that side B'C' is twice as long as side BC. Use the distance formula to compute the length of side BC: Length of BC = √ [ (x C -x B) 2 + (y C -y B) 2] Length of B'C' = 2·BC WebBounds for elements of a triangle expressed by R, r, and s 103 with equality if and only if ABC is equilateral. If ABC is an acute triangle, this inequality can be improved. Indeed, by (10) we have cosA ≤ r R + 1− 2r R. In our hypothesis, cosA 0. Thus, after squaring we obtain
