$Circle with center O, two radii to points A and B forming central angle 130°, minor arc AB highlighted.$

Circle $O$ has center $O$ . Central angle $AOB = 130\degree$ . What is the measure, in degrees, of minor arc $AB$ ?

In circle $O$ , central angle $MON = 110\degree$ . What is the measure, in degrees, of major arc $MN$ ?

An inscribed angle intercepts an arc of 96°. What is the measure, in degrees, of the inscribed angle?

$Circle with inscribed angle ACB = 37° at point C on the circle, intercepted arc AB highlighted below.$

Inscribed angle $ACB$ measures 37°. What is the measure, in degrees, of intercepted arc $AB$ ?

Points $A$ , $B$ , $C$ , and $D$ lie on a circle in that order. Inscribed angle $ACB = 55\degree$ and inscribed angle $ADB$ both intercept arc $AB$ (the arc not containing $C$ or $D$ ). What is the measure of angle $ADB$ ?

27.5°

55°

110°
