Draw rough diagrams of two angles that have, (a) One point common (b) Two points in common (c) Three points in common (d) Four points in common (e) One ray in common

Solution:

An angle is formed by two rays or lines that share a common endpoint (known as a vertex). Letus use the concept of angles in answering the question.

a) One point common

∠AOB and ∠COD have point O in common.

b) Two points in common

∠AOB and ∠BOC have points O and B in common.

c) Three points in common

∠AOB and ∠BOC have points O, D, and B in common.

d) Four points in common

∠AOB and ∠BOC have points O, D, E, and B in common.

e) One ray in common

OB is a common ray between ∠1 and ∠2.
