The measure of an angle inscribed in a semicircle is equal to ______?
The measure of an angle inscribed in a semicircle is equal to ______?
Explanation
A semicircle is half of a circle.
A central angle which is subtended by a semicircle has a measure of 180°.
A circle is associated with a complete rotation, which is 360°.
A semi-circle is associated with half of a rotation which is 180°.
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees.
