To tell: whether m∠DOC=180

Expert Solution & Answer

Answer to Problem 30CE

m∠DOC=180

Explanation of Solution

Given information:

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 1.4, Problem 30CE

One of the few things we can assume in geometry, is that lines that appear straight are straight.

Straight angles are composed of two opposite straight lines or half-lines called rays.

Rays OD and OC point in opposite directions.

Therefore they are 180 degrees apart and form a straight angle.
