Which transformation will map octagon PQRSTVWZ onto itself? Select each correct transformation

a. reflectioning over QV
b. reflectioning over RV
c. reflectioning over TX
d. rotating 45 degrees clockwise around point Z
e. rotating 135 degrees clockwise around point C
f. rotating 90 degrees counterclockwise around point C​

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
