Theorems and Postulates that prove two triangles are. . WebThe SSS theorem requires that 3 pairs of sides that are proportional. In pair 1, all 3 sides have a ratio of $$ \frac{1}{2} $$ so the triangles are similar. In pair 2, two pairs of sides have a ratio of $$ \frac{1}{2}$$, but the ratio of.

WebWe can find the areas using this formula from Area of a Triangle: Area of ABC = 12 bc sin(A) Area of PQR = 12 qr sin(P) And we know the lengths of the triangles are in the ratio x:y. q/b = y/x, so: q = by/x. and r/c = y/x, so r.
