Points, Lines, Angles, and Planes Exercises

Answer

Line x (also known as GE, ED, and GD) and w (otherwise known as BC) appear the most parallel.

Answer

Three other names for ∠EDB are: ∠GDA, ∠GDB, and ∠EDA.

Answer

∠BED and ∠GEF are vertical angles, as are ∠BEG and ∠DEF. While there are plenty of other vertical angles in the picture, they're like the horde of relatives from out of state whose names you never seem to remember. You know they're there, but just don't call them anything.

Answer

The angles ∠CBA and ∠DBE are both adjacent to ∠DBC.

Answer

∠EDB and ∠BED are neither adjacent nor vertical angles. They don't share a vertex (necessary for adjacent angles) and they aren't opposite intersecting lines (the definition of vertical angles).

Answer

Yes, ∠ABE shares a vertex and a side with ∠DBF so they are adjacent.
