Question

1. (l9) identify what each of the following represents: $overline{ab}$; $overline{de}$; and $angle mno$. a. $overline{ab}$ is a line, $overline{de}$ is a line segment, and $angle mno$ is an angle. b. $overline{ab}$ is a ray, $overline{de}$ is a line, and $angle mno$ is an angle. c. $overline{ab}$ is a line segment, $overline{de}$ is a line, and $angle mno$ is an angle. d. $overline{ab}$ is a line segment, $overline{de}$ is a ray, and $angle mno$ is a plane. e. $overline{ab}$ is an angle, $overline{de}$ is a line, and $angle mno$ is a ray. 9. (l12) if an obtuse angle is bisected, are the resulting smaller angles acute, right, or obtuse?

Explanation:

Step1: Recall geometric - figure definitions

$\overline{AB}$ has two endpoints, so it's a line - segment. $\overline{DE}$ has two endpoints, so it's a line - segment. $\angle MNO$ is formed by two rays sharing a common endpoint, so it's an angle.

Answer:

$\overline{AB}$: line segment; $\overline{DE}$: line segment; $\angle MNO$: angle
