The correct answer is D. An obtuse angle measures more than a right angle (which is 90 degrees) but less than a straight angle (which is 180 degrees).

To understand this concept, first, you should know what a right angle is. A right angle is formed when two lines intersect each other and create a square corner, which is 90 degrees. So anything less than 90 degrees is called an acute angle.

To determine if an angle is obtuse, you need to measure it. You can use a protractor, a tool specifically designed to measure angles. Begin by placing the protractor on the vertex (the point where the two lines intersect). Ensure that one of the lines aligns with the 0-degree line on the protractor. Then, look at the degree measurement where the second line intersects the protractor. If the measurement is greater than 90 degrees but less than 180 degrees, then the angle is obtuse.

Alternatively, you can use the knowledge that a straight angle measures 180 degrees. If an angle is more than 90 degrees (a right angle) but less than 180 degrees (a straight angle), it is obtuse.

So, in summary, an obtuse angle measures more than a right angle (90 degrees) but less than a straight angle (180 degrees).
