Question

The angle shown is in standard position. Select
the possible measures of the angle.
-450°
-360°
-270
-90°
90°
270°
360°
450°

Answer 1

Explanation:

The vertex of an angle is in standard position lies at the origin while one ray lies on the positive x-axis.  So we call:

• Initial side: The ray on the x-axis
• Terminal side: The other ray

So the representation of this definition is shown in the first figure below. The second figure shows that the angle measures:

$90^{\circ}$

But this angle is also:

$-270^{\circ} \\ \\ \\ 360^{\circ}+90^{\circ}=450^{\circ}$

So correct options are:

$-270^{\circ} \\ \\ 90^{\circ} \\ \\ 450^{\circ}$
