Angle of triangle ABC a triangular prism of length3 metres is shown. AB=20cm, BC=29cm, angle BAC=90˚. calculate the area of triangle ABC. give your answer in cm² and show all your working.

Which composition of similarity transformations maps polygon abcd to polygon a'b'c'd'? a dilation with a scale factor less than 1 and then a reflection a dilation with a scale factor less than 1 and then a translation a dilation with a scale factor greater than 1 and then a reflection a dilation with a scale factor greater than 1 and then a translation

Can someone me out here and the tell me the greatest common factor
