Question

use the diagram above to answer the following question. 1. name ∠3 in two other ways. ∠ and ∠

Explanation:

An angle can be named by the vertex alone if there is only one angle at that vertex. Or it can be named using three - point notation where the vertex is the middle point. Here, the vertex is \(B\). For \(\angle3\), two other ways to name it are by using the three - point notation \(\angle DBC\) (with \(B\) as the vertex) and \(\angle CBD\) (the order of the non - vertex points doesn't matter when naming the angle in this way).

Answer:

\(\angle DBC\), \(\angle CBD\)
