The figure below shows segments ac and ef which intersect at point b. segment af is parallel to segment ec.. which of these facts is used to prove that triangle abf is similar to triangle cbe? . angle afb is congruent to angle ceb because corresponding angles are congruent.. angle afb is congruent to angle ceb because corresponding angles are congruent.. line segment af is congruent to line segment ec because parallel segments are congruent.. line segment ab is congruent to line segment fb because legs of an isosceles triangle are congruent.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
