• The intersection

• The vertex

• The midpoint

Which symbol is used to indicate an angle in the short form?

• ⊥

• ∩

• ∥

• ∠

In the long form of naming an angle, where should the vertex be placed?

• At the beginning

• It doesn't matter

• At the end

• In the middle

When can both the long and short forms be used to name angles?

• When there are three rays sharing the same endpoint

• When there are two rays sharing the same endpoint

• When there are no rays

• When there is only one ray

Why can only the long form be used when there are three rays sharing the same endpoint?

• To avoid confusion

• Because it's easier

• Because the short form is incorrect

• Because the vertex is not needed

What is the first step in drawing an angle named DEF?

• Draw a line

• Identify the vertex

• Label the rays

• Draw a circle
