Helena was curious if quadrilaterals QRST and XYZW were congruent, so she tried to map one figure onto the other using transformations: Helena concluded: "It's not possible to map QRST onto XYZW sing a sequence of rigid transformations, so the quadrilaterals are not congruent." What error did Helena make in her conclusion? WILL GIVE BRAINLIEST!!!

just needed some points but try socratic

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
