Hello, could I please get some help on these? Thank you!

1pt The diagram below shows three similar triangles, \\ RST ~\\ RDS ~\\ SDT. Danielle knows the corresponding sides of these similar triangles have proportional lengths. Using this fact, she wants to set up some proportions to help her prove the Pythagorean Theorem, a + b2 = c2 . Which of the following proportions would be the most helpful in her proof? Select all that apply. b a f e d R D C O A. - = OB. : O C. = 7 O D. DE. = 7 OF. S = -1pt A dilation of A ABC produces similar _ AB'C', with B'C' parallel to segment BC. Use the information given to prove that a line drawn parallel to one side of a triangle divides the other two sides proportionally. Given: BC is parallel to BIC' . Prove: AC B'B ' Drag and drop the correct reasons into the table below to complete the proof. AA Similarity SSS Similarity SAS Similarity : :: : :: Partition postulate Definition of midpoint Vertical angles ::8 ::: Corresponding angles Side proportionality of parallel lines of similar triangles ::: B C Statements Reasons 1. ZAC'B' ZACB and ZAB'C' = ZABC 2. AABC ~ AAB'C' N 3. AC AB' W AC AB 4. AC = AC' + C'C and 4. AB = AB' + B'B1pt A line and a point external to the line are given. P. Given: a line and point P. Order the following steps needed to nd the line through point P that is parallel to the given line. Step 1 Step 2 Step 3 Step 4 unu-l-mm-uumruln IDES
