Question

If the number of endpoints in a line, ray and a line segment are represented by X, Y, and Z, then find the value of X + Y + Z [2 MARKS]

Options:

Answer: Option A
:

Steps: 1 Mark
Result: 1 Mark
The number of endpoints in a line is zero.
$\Rightarrow X = 0$
The number of endpoints in a Ray is 1
$\Rightarrow Y = 1$
The number of endpoints in a line segment is 2.
$\Rightarrow Z = 2$
$∴ X + Y + Z = 3$
