Sylvia’s aunt asked her to help cut out fabric for a quilt. The figure shows the pattern of one section that is made of triangles. What degree of rotation clockwise about point B should Sylvia use to prove that ΔABC (pre-image) and ΔIBH (image) use the same amount of fabric? http://static.k12.com/calms_media/media/1572500_1573000/1572840/1/466824e26168a20221394790a85af228c7d87cda/MS_IMC-141215-110505.jpg I'm pretty sure it's 90 degrees clockwise
