Please Help.. I am struggling to answer this inspite of trying to re read theorems.. I couldn't answer anything.. if you can solve this please teach me the steps.
So i could answer them in the future..
To find the measure of an angle in a circle, you need to know the central angle and the radius of the circle. The measure of the angle is equal to the length of the arc it intercepts divided by the length of the radius, multiplied by 180 degrees.
The central angle of a circle is an angle whose vertex is at the center of the circle and whose sides pass through two points on the circle. It is measured in degrees and is equal to the arc length it intercepts divided by the radius of the circle.
To find the measure of an inscribed angle in a circle, you need to know the measure of the central angle that intercepts the same arc as the inscribed angle. The measure of the inscribed angle is half of the measure of the central angle.
The measure of an inscribed angle is always half of the measure of the central angle that intercepts the same arc. This relationship is known as the Inscribed Angle Theorem.
To find the measure of a tangent angle in a circle, you need to know the measure of the central angle that intercepts the same arc as the tangent angle. The measure of the tangent angle is equal to half of the difference between 180 degrees and the measure of the central angle.
