Transformations from instructions
I will draw on the board the picture
translate the triangle down 3
the figure formed by two rays or line segments
angle
single lower case letter (ie a) notates what
a line or line segment
Object that is reflected (like a mirror) over some axis
reflection
I will draw on the board the picture
rotate the rectangle 90
see board
a line with only one defined endpoint that extends infinitely in the other direction
ray
two letters (generally uppercase) notate what
a ray or line segments
object moved up, down left or right
translation
I will draw on the board the picture
reflect the rectangle over x and y axis
see board
Something that has been PROVEN using know definitions and previously proven statements (builds on itself)
theorem
something notated by a single capital letter
point
this transformation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point.
rotation
I will draw on the board the picture
reflect the triangle over the line y=x
see board
A statement taken to be true
axiom or postulate
an image post transformation is notated by.. and called (verbally)
a' or a prime
translations change what about the shape
the location
I will draw on the board the picture
a statement that can be written in the form “p if and only if q.” This means “if p, then q” and “if q, then p.”
biconditional statement
Notated by three capital letters (ie ABC) (we haven't talked about this yet but try to guess!)
a triangle
Dilations increase or decrease by what
a constant factor
