Do you remember what a measure of turn is?
Use this applet to help you explore different measures of turns.
Based on the circle above, a quarter turn indicates a 90\degree degrees, a half turn indicates a 180\degree degrees, and a full turn of circle indicates a 360\degree degrees.
A right angle is a:
A right angle is a quarter turn around a circle.
Let's look at slides first, where we change the position of a shape. Slides are also called translations.
Choose the picture that shows a translation.
A slide or translation is when the object moved along a straight line.
Now let's look at flips in this video. Flips are also called reflections.
Choose the picture that shows a reflection.
A flip or reflection is when the object is flipped or reflected across a line, and the result is a mirror image.
Now let's learn about turns, which change the orientation of a shape or object. Turns are also called rotations.
Choose the picture that shows a rotation.
Translations, reflections and rotations change the position or orientation of the shape, but the shape itself stays the same.
