Symmetry and Algebra
100
A shape that has all congruent sides and interior angles
What is a regular polygon?
100
The tool used in geometry to construct a variety of geometric figures. It has a point which is connected to a mechanism that holds a pencil.
What is a compass?
100
A transformation where size and shape is preserved.
What is an isometric transformation?
100
You read this notation like this... "g of x"
How do you read "g(x)"?
200
This is another word for isometric transformation
What is a rigid motion?
200
The construction that forms two lines that never intersect with each other.
What is the parallel line construction?
200
This transformation notation describes a reflection over the x-axis.
What is "Rx-axis"?
200
The smallest angle you can rotate a shape before it maps back onto itself.
The angle of rotational symmetry
300
a figure which starts at a point and extends indefinitely in a single direction from that point.
What is a ray?
300
The construction where any angle is divided in half into two smaller congruent angles.
What is an angle bisector construction?
300
Dilation and stretch.
What are non-isometric transformations
300
The number of times a shape maps back onto itself before it returns to it's original position
What is the order of rotational symmetry?
400
two lines which never intersect
What are parallel lines?
400
The construction which divides a line segment into two congruent line segments and forms 4 right angles.
What is the perpendicular bisector construction?
400
This is a transformation that moves a shape around a point in a circular motion and its notation looks like this Ro,270°
What is a rotation?
400
This regular polygon has exactly 4 lines of symmetry.
How many lines of symmetry does a square have?
500
two lines that intersect and form four right angles
What are perpendicular lines?
500
The key figure used in forming any construction. It is part of a circle and is created using a compass
What is an Arc?
500
(x,y) ---> (x+3,y-5)
What is a "coordinate rule" that requires the shape being transformed to shift 3 units to the right and -5 units down?
500
This describes a relationship between two sets of numbers where every input has exactly one output.
What is a function?
M
e
n
