50. The correct answer is (C).∆PQT ≅∆RST and ∆PST ≅∆RQTIn ∆PQS, is a median, since the diagonals of a parallelogram bisect each other. Consequently,∆PST and ∆PTQ are equal in area as they have equal bases (ST = TQ) and a common altitude (perpen-dicular from P to ). Therefore, all four triangles are equal in area.

Math Level ICDirections: For each question in the sample test, select the best of the answer choices and blackenthe corresponding space on this answer sheet.Please note:(a) You will need to use a calculator in order to answer some, though not all, of the questions in thistest. As you look at each question, you must decide whether or not you need a calculator for thespecific question. A four-function calculator is not sufficient; your calculator must be at least a scien-tific calculator. Calculators that can display graphs and programmable calculators are also permitted.(b) The only angle measure used on the Level IC test is degree measure. Your calculator should beset to degree mode.(c) All figures are accurately drawn and are intended to supply useful information for solving theproblems that they accompany. Figures are drawn to scale UNLESS it is specifically stated that afigure is not drawn to scale. Unless otherwise indicated, all figures lie in a plane.(d) The domain of any function f is assumed to be the set of all real numbers x for which f(x) is areal number except when this is specified not to be the case.(e) Use the reference data below as needed.REFERENCE DATASOLID
