WebArea. The area of a trapezoid is calculated by multiplying the average width by the altitude. See Trapezoid definition (coordinate geometry) to see how the side lengths and altitude are found. (Note too that the median length is the same as the average width.) In the figure above, drag any vertex of the trapezoid and note how the area is ...

WebWhen you compare the ratios of the perimeters of these similar triangles, you also get 2 : 1. This leads to the following theorem. Theorem 60: If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b. Example 1: In Figure 2, Δ ABC ∼ Δ DEF. … The four properties that follow are not difficult to justify algebraically, but the … There are several different angles associated with circles.
