Triangle segments and centers
A segment that divides an angle into two congruent angles.
What is angle bisector?
This transformation is NOT a rigid motion.
What is dilation?
The sum of all 4 angle measures of a quadrilateral.
What is 360 degrees?
A segment with one endpoint at the center and one endpoint on the circumference.
What is radius?
This formula is used to show that two segments are parallel.

Staten Island Ferry
The intersection point of all three medians of a triangle.
What is centroid?
This transformation shifts a figure vertically and horizontally.
What is translation?
This definition of this quadrilateral is that both pairs of opposite sides are parallel.
What is parallelogram?
