Now we know that the lengths of sides in triangle S are all 648 times the lengths of sides in triangle R. Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Triangles ABC and PQR are similar and have sides in the ratio xy.
Two triangles are similar if any of the following is true.
Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Qb yx so. Now we know that the lengths of sides in triangle S are all 648 times the lengths of sides in triangle R. Similar Triangle Formula A X B Y and C Z ABXY BCYZ ACXZ.
