Which triangle is similar to triangle PQR using the Pieces of Right Triangles Similarity Theorem? Triangle SRP has measure of angle SRP equal to 90 degrees. Q is a point on the hypotenuse SP such that the segment QR is perpendicular to PS. T is a point outside the triangle on the left of S so that triangle QTS has the measure of angle QTS equal to 90 degrees. Triangle RQS Triangle TSQ Triangle QST Triangle SRQ
