Who is the coolest teacher ?
Ms.Nicole
A dilation with a scale factor less than one. The image is smaller than the original figure.
Reduction
Alternately, you could flip a figure so that it is flipped across a line of reflection.
Reflection
a movement in a figure's position, shape, or size. Translations, reflections, and rotations are the 3 types.
Figure B is a reflection, or flip, of Figure A
Transformation
What is the area of a rectangle that has a length of 6 and the width of 12
72
length x width = area
The sign (') is used to show that a transformation or a sequence has been made and it may also be utilized to show how many, as in ("), ("'"), etc.
Prime
a rigid movement that shifts each point of a figure by the same distance and in the same direction.
Translation
a figure that can be rotated around a fixed point.
Center of Rotation
a line that a figure reflects across.
Line of reflection
542-320=
222
rigid motion that revolves a figure around the center of rotation, which is a fixed point.
Rotation
683-210=
437
what is the point where two lines meet called?
vertex
what is the name of an angle that is 90 degrees
right angle
The outcome of a transformation of a line, figure, or point.
Image
Lines that are the same and never intersect are called
parallel lines
the amount of degrees that a figure has been rotated.
Angle of Rotation
a side and the extension of an adjacent side forming an angle.
Exterior Angle of a Triangle
the first point, line, or figure before a transformation is made.
Pre-Image
true or false: if you are reflecting an image over the Y- axis, will you being going ?
Horizontally or vertically ?
horizontally
starting from a set center, moves each point along the ray through the point and multiplies distances from the center by regular scale factors. The vertex and its image after the dilation are the same point if the center of dilation is a vertex of a figure.
Dilation
angles that are located in corresponding places and on the same side as a transversal.
Corresponding Angles
What does the word dilation mean in terms of transformations?
to make an image smaller
Which way does counter clockwise turn?
