Of the 35 students in my class, 11 practice taekwondo, 11 play piano, and 20 take lessons at AOPS. 4 students play piano and go to AOPS, 3 students do taekwondo and play piano, 5 students go to AOPS and practice taekwondo, and three students do none of these, How many students do all three?

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
