Hypothesis: The “IF” portion of an “If-Then” statement. Also part of the

Bisect: A ray that separates given angles into 2 smaller, congruent angles
Arc: Part of a circle determined by 2 points on a circle and every point
between them.
Radius: A line segment joined at the center of the circle to a point on the
circle
Intersect: Elements that 2 sets have in common.
Postulates: A statement assumed to be true
