How do we measure an angle?
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
How do you use a half-circle protractor to measure an angle?
Place the center point of the protractor at the vertex of the angle and one of the lines of the angle along the zero line of the protractor. The measure of the angle will then be where on the protractor's angular scale the other line of the angle lies.
What is defined to be an arc that has an central angle with the measure of 180 degrees?
If the arc is circular, such a figure is a semicircle or half circle.
Which of the following is defined to be an arc that has a central angle with the measure of 180?
A 180-degree arc is also called a half-circle.
What does a picture of a straight angle look like?
A straight angle is a half circle.
The measure of an inscribed angle in a circle is the measure of the intercepted arc.?

What is the angle measure or degree for one half?
180 degrees, if you mean a half circle
What angle measure does a semicircle have?
A semi-circle, half a circle, by definition is 180 degrees, half of a rotation. A whole circle has a whole rotation, which is 360 degrees.
A angle has measure of 180?
An angle with a measure of 180 degrees will look like a straight line with the vertex being a point in the center. Since a complete circle is 360 degrees, opening an angle to 180 degrees traces out exactly half a circle.

A 180-degree arc is also called a half-circle.
Is it true or false that the measure of a tangent-chord angle is twice the measure of the intercepted arc inside the angle?
It is true that the measure of a tangent-chord angle is half the measure of the intercepted arc inside the angle. When a tangent line intersects a chord of a circle, it creates an angle between the tangent line and the chord, known as the tangent-chord angle. If we draw a segment from the center of the circle to the midpoint of the chord, it will bisect the chord, and the tangent-chord angle will be formed by two smaller angles, one at each end of this segment. Now, the intercepted arc inside the tangent-chord angle is the arc that lies between the endpoints of the chord and is inside the angle. The measure of this arc is half the measure of the central angle that subtends the same arc, which is equal to the measure of the angle formed by the two smaller angles at the ends of the segment that bisects the chord. Therefore, we can conclude that the measure of a tangent-chord angle is half the measure of the intercepted arc inside the angle.
The measure of an acute angle is half the measure of an obtuse angle.What is the measure of an obtuse angle?
The measure of the obtuse angle would then be double that of the acute angle.
