If angle A is congruent to itself by the Reflexive Property, which transformation could be used to prove ΔABC ~ ΔADE by AA similarity postulate? triangles ABC and ADE, in which point B is between points A and D and point C is between points A and E Translate triangle ABC so that point B lies on point E to confirm ∠B ≅ ∠E. Translate triangle ABC so that point C lies on point E to confirm ∠C ≅ ∠E. Dilate ΔABC from point A by the ratio segment AD over segment AB to confirm segment AD ~ segment AB. Dilate ΔABC from point A by the ratio segment AE over segment AC to confirm segment AE ~ segment AC.

Mr. brettler is hanging up a 5-foot tall rectangular welcome sign in the gym. he has drawn a sketch on a coordinate grid. he has the lower vertices of the sign at (9, –3) and (–6, –3). where would the upper vertices be on the grid?

Which is f(5) for the function –2x2 + 2x - 3?

Have you ever been in the middle of telling a story and had to use hand gestures or even a drawing to make your point? in algebra, if we want to illustrate or visualize a key feature of a function, sometimes we have to write the function in a different form—such as a table, graph, or equation—to determine the specific key feature we’re looking for. think about interactions with others and situations you’ve come across in your own life. how have you had to adjust or change the way you represented something based on either the concept you were trying to describe or the person you were interacting with? explain how the complexity or layout of the concept required you to change your style or presentation, or how the person’s unique learning style affected the way you presented the information.
