Whаt is the rаtiо оf the cоrresponding sides? A geometric diаgram shows two triangles stacked vertically. The upper triangle is labeled X, Y, and Z. Points Y and Z form a horizontal base, with Y on the left and Z on the right. Point X is centered above the base, forming the top vertex. Below it is a smaller triangle is labeled T, U, and V. Points U and V form a horizontal base, with U on the left and V on the right. Point T is centered above the base. Both triangles have a similar orientation, with a horizontal base and a single top vertex centered above the base.
