To find the angle of a triangle within a circle segment, you first need to determine the central angle of the circle segment. Then, you can use the properties of triangles inscribed in circles to find the angle. The angle of the triangle within the circle segment will be half the measure of the central angle.

You also need the measure of the central angle because arc length/2pi*r=measure of central angle/360.
In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.
central angle central angle
the measure of the inscribed angle is______ its corresponding central angle
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?

The central angle of the circle is the angle around a point and so, be definition, it must be 360 degrees.
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
