Unit 2 Day 3 Rotations

Unit 2 Day 3 RotationsMr. KuglerFrank H. Peterson Academies of TechnologyWarm - UpThis will be collected Write down 5 times (Hour : Minutes) that will result in the hands on the face of an analog clock to be at a 90 angle.Bonus Q: If the hour and minutehand are pointing at consecutivenumbers, what is the measurementof their angle. In other words, howmany degrees are there between two numbers next to each other ona clock face?

Rotations (Ch. 9.3)Essential QuestionHow does a rotation change the image of a figure?

On the Back of the Third PageSummary:For 0 and 360 Nothing ChangesFor 90 Counter Clockwise and 270 Clockwise Switch X and Y and negate the original y value.For 90 Clockwise and 270 Counter Clockwise Switch X and Y and negate the original x value.For 180 Negate both X and Y but do not switch them.Problem 2 Pg 563
