Rigid Transformations
A translation is also known as this.
What is a slide?
A figure has symmetry if there is a rigid transformation which takes the figure to this.
This is the tool used to construct a circle in geometry.
What is a compass?
You need these tools to draw a bisector.
What is a compass and a straightedge?
An equilateral triangle can be constructed using these.
What are at least 2 circles?
A rigid transformation does not change these two things.
What are size and shape?
An equilateral triangle has this many lines of symmetry.
What is 3?
What is a center point?
To create an angle bisector, you must draw a circle around the center point, and then you must have these.
What are two points equidistant from the center point on the angle?
Two lines that never touch infinitely are called this.
If a transformation takes A to A', then A is the original and A' is the...
What is an image?
Do ALL figures have a line of symmetry?
What is no?
This will connect the center point to the outside of the circle at a point.
What is a radius?
In order to bisect a segment given a point not on a line, you need this.
What is a circle around the point that intersects the line segment in two places?
When constructing a square, in order to ensure that all sides are congruent, describe what you must do.
What is measure using a compass?
What is a reflection?
Rotation symmetry requires this to take a figure onto itself.
What is a rotation?
A circle has how many degrees total?
What is 360?
Given an equilateral triangle, if you bisect an angle, the segment opposite the angle will also have this.
What is a perpendicular bisector?
What is two?
Inn this type of transformation, every point of a figure moves in a circle around the center.
What is a rotation?
What is a circle?
Describe the definition of a circle.
What is the set of all points equidistant from center of the circle?
A bisector is called a bisector because of this.
What is because it splits an angle or a segment into two parts?
In order to construct a hexagon, you must do this.
What is draw several circles of the same radius centered at the intersection points?
