Transformations
Any transformation where the original shape and the image are congruent.
What is a rigid transformation?
Congruent angles that are opposite of each other.
What are vertical angles?
This tool allows you to make "perfect" circles.
What is a compass?
If you can perfectly put one shape onto another using transformations then the two shapes are __________.
What is congruent?
What is an equation?
These two things are needed in order to do a translation/slide.
What is distance and direction?
Ms. Jolly will draw a picture on the board for this one.
What are corresponding angles?
The ________ splits a line in half and creates a 90 degree angle.
What is a perpendicular bisector?
The new shape after a transformation.
What is an image?
Something you believe to be true but haven't proven yet.
What is a conjecture?
These three things are needed in order to do a rotation.
What is point of rotation, direction, and angle of rotation?
What do we know about all angles in a triangle?
They add up to 180 degrees
This construction is used to cut an angle in half.
What is angle bisector?
If you can "spin" a shape and it lands back where it started, then it has ___________.
What is rotation symmetry?
This line cuts through two parallel lines.
What is a transversal?
What is a directed line segment?
Congruent angles that are on opposite sides of the transversal and are both inside of the parallel lines.
What are alternate interior angles?
This tool allows you to measure angles.
What is a protractor?
If you can "fold" a shape onto itself then it has ___________.
What is reflection symmetry?
A map with a bunch of perpendicular bisectors. It is used to tell you where the nearest location is.
What is a Voronoi Diagram?
When connecting corresponding points after a reflection, the line of reflection acts as __________.
What is a perpendicular bisector?
The set of all points equidistant from 2 points.
What is the perpendicular bisector?
A shape where all the sides and angles are congruent.
What is a regular polygon?
A shape has reflection symmetry if you can draw this.
What is a line of symmetry?
A repeating pattern with no overlaps or gaps.
What is a tessellation?
