A line segment is part of a line that has two endpoints and contains every point between its endpoints. A ray is a line that has one endpoint and continues infinitely in the other direction.
The last option is correct. If two sides of a triangle are congruent, then the angles opposite those sides are congruent. This is probably because the sides are equal.
A rotation is an isometric transformation that turns every point of a figure through a specified angle and direction about a fixed point.
To describe a rotation, you need three things:
Direction (clockwise CW or counterclockwise CCW)
Angle in degrees
Center point of rotation (turn about what point?)
The most common rotations are 180° or 90° turns, and occasionally, 270° turns, about the origin, and affect each point of a figure as follows:
