Explanation:
#"Since we are given the lengths of 3 sides in both triangles"#
#• " check if corresponding sides are proportional"#
#"consider the ratios of "color(blue)"corresponding sides"#
#color(red)(BD)/color(blue)(RT),color(red)(BC)/color(blue)(RS)" and "color(red)(CD)/color(blue)(RS)#
#color(red)(BD)/color(blue)(RT)=810/1395=18/31#
#color(red)(BC)/color(blue)(RS)=666/1147=18/31#
#color(red)(CD)/color(blue)(RS)=450/775=18/31#
#"thus by SSS "triangleRST" is similar to "triangleBCD#
