How many lines are determined by two points?
a. 0
b. 1
c. 2
d. infinite

Option 'B' is correct.

Step-by-step explanation:

Since we have given two points.

And we know the definition of line which states that " A line is formed by two points and it can be extended from both the sides."

So, From two points, there must be 1 line .

Hence, one line is determined by two points.

Therefore, Option 'B' is correct.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
