Angle Measures in Circle

Front

What is the measure of an angle formed by two tangents drawn from a point outside a circle to the circle?

Back

The measure of the angle formed by two tangents drawn from a point outside a circle is equal to half the difference of the measures of the intercepted arcs.

If the measure of an arc is 100°, what is the measure of the angle formed by the tangents to the circle at the endpoints of the arc?

What is the relationship between the angle formed by two chords that intersect inside a circle and the arcs they intercept?

Back

The measure of the angle formed by two intersecting chords is equal to half the sum of the measures of the intercepted arcs.
