 This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

Reflections and Rotations!

Hello everyone!

I hope you had a fantastic Easter! I had a wonderful time with my family. We made a delicious bunny cake!

This week in geometry we learned about a type of transformation called a reflection. Reflections flip the given shape. The two necessary components of a reflection are an object, or preimage, and a line of reflection.

There are two rules of reflections:

Rule One: If a preimage is on the line of reflection, then it will be itself when you find the image.

Rule Two: The line of reflection is the perpendicular bisector of the segment whose endpoints are A and A prime.

We also learned about rotations this week, which rotate/turn an image around a specific point. The three components of a rotation are the point of rotation, the angle of rotation, and the direction (either clockwise or counterclockwise).

I hope that I have helped to give you a basic idea of these two transformations! Have a great week! :)
