Rigid Motion
A movement along a plane that keeps the shape the same only changes the location on the plane.
What is rigid motion?
The two rigid motions that would move a figure 90 degrees around point "p" then reflected over the x-axis
What is rotation and reflection?
two angles who add together to make 180 degrees
Supplementary Angles
What is the Pythagorean Theorm
a2+b2=c2
a transformation that slides the figure a fixed distance
What is Translation?
Figure ABC was moved two inches up and three to the right, then rotated 180 degrees counterclockwise . What would you do to place figure A'B'C' back onto figure ABC?
rotate the figure 180 degrees clockwise then three inches to the left and two inches down.
two angles that add up to 90 degrees
complementary angles
The only triangle that the Pythagorean Theorem works for?
Right Triangle
A transformation that produces a mirror image of a figured over a line
What is reflection?
The opposite of 270 degrees clockwise?
90 degrees counterclockwise.
The straight line that cuts a set of parallel lines.
Transversal
What is the leg opposite the 90 degree angle called?
Hypotenuse
A transformation that turns a figure around a specific point?
What is rotation?
the opposite of 180 degrees clockwise
180 degrees counterclockwise.
The measurement of a straight line
180 degrees
The length of C if A= 6 and B=10
Square root of 136
two rigid motions that are preformed after each other to move a figure along a plane.
What is a sequence of rigid motions?
What tools are used to preform translation, rotation, and reflection?
transparency film, protractor, straight edge, and math mirror. (3/4 needed)
an adjacent angle equals 108 degrees, what is the opposite angle from the adjacent angle going to equal if it's (3x-6)What does x equal?
X=58
The length of one of the legs if A= 5 and C=13
B=12
