Explanation:

1. A flat surface extending infinitely in all directions is a plane.
2. An angle measuring between 90° and 180° is an obtuse angle.
3. The point that bisects a line - segment is the mid - point.
4. The supplement of a right angle (90°) is a right angle (180° - 90°=90°).
5. Two adjacent angles formed by two intersecting lines form a linear pair.

Answer:

1. g. Plane
2. f. Obtuse Angle
3. e. Midpoint
4. h. Right Angle
5. d. Linear Pair
