Answer:
a straight line
Step-by-step explanation:
<u><em>The complete question is</em></u>
Which has a measure that is equal to the sum of the measures of the interior angles of a triangle?
A) a straight line
B) a circle
C) a right angle
D) an obtuse angle
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Verify all the options
Option A) a straight line
The measure of the angle on a straight line is equal to 180 degrees.
Option B) a circle
The central angle of a circle is equal to 360 degrees
Option C) a right angle
The measure of a right angle is 90 degrees
Option D) an obtuse angle
An obtuse angle is greater than 90 degrees but less than 180 degrees
therefore
The answer is a straight line
