Week 1
A precise location or position in space. It has no size, width, length, or thickness.
What is a point?
A ray or line that divides an angle into two equal smaller angles.
What is an angle bisector?
this slides every point of a shape the same distance in the same direction
What is a translation?
the set of all points on a line between two endpoints
What is a line segment?
A line that divides a line segment into two equal parts and forms a right angle to that segment
What is a perpendicular bisector?
this flips a shape over a line to create a mirror image
What is a reflection?
the point or set of points where two or more geometric figures, such as lines, curves, or planes, meet or cross each other
What is an intersection?
a polygon where all of the sides are congruent and all of the angles are congruent
What is a regular polygon?
this produces an image that is the same shape as the original figure but is a different size
What is a dilation?
the set of all points in a plane that are the same distance from a fixed point called the center
What is a circle?
A regular polygon that is made up of 4 congruent segments that create 4 right angles
What is a square?
Figures that have the same shape and the same size. One can be transformed into the other using rigid transformations
What are congruent figures?
Two lines in the same plane that never intersect or meet, no matter how far they are extended in either direction
What are parallel lines?
The diagonals of a square are _______ of each other
What are perpendicular bisectors?
Transformations that move a figure without changing its size or shape. The figure is congruent to its image after the transformation.
What are rigid transformations?
