How to calculate similar triangles
WebWe can see that the small triangle fits into the big triangle four times. So when the lengths are twice as long, the area is four times as big. So the ratio of their areas is 4:1 . We can also write 4:1 as 2 2:1. The General … WebThe scale factor of these similar triangles is 5 : 8. Example 3: The perimeters of two similar triangles is in the ratio 3 : 4. The sum of their areas is 75 cm 2. Find the area of each triangle. If you call the triangles Δ 1 and Δ 2, then. According to Theorem 60, this also means that the scale factor of these two similar triangles is 3 : 4.
