Two quadrilaterals abcd and efgh are congruent if they have the same side lengths and the same angles. we write abcd = efgh if and only if abc = efg bcd = fgh adc = ehg bad = feh ab =ef bc = fg cd = gh ad = eh is there any 4 letter rule (like sasa eg.) that can be used to determine when two quadrilaterals are equivalent. find one 5 letter rule that works for quadrilaterals. briefly explain and illustrate your rule. find a counter example to show that ssass cannot be a rule. (that is, draw two non-congruent quadrilaterals with congruent side lengths and one congruent angle).
