M3A 2.09c Mixed Circle Theorems Practice

Front

What is the measure of angle in a circle formed by two secants intersecting outside the circle?

Back

The measure of the angle is half the difference of the measures of the intercepted arcs.

Front

What is the relationship between the angles formed by two intersecting chords in a circle?

Back

The measure of the angle is equal to the average of the measures of the arcs intercepted by the angle and its vertical angle.

Front

How do you find the measure of a major arc in a circle?

Back

The measure of a major arc is 360° minus the measure of the corresponding minor arc.

Front

What is the formula for the angle formed by two secants that intersect outside a circle?

Back

Angle = 1/2 (larger arc - smaller arc).

Front

What is the measure of an inscribed angle in a circle?

Back

The measure of an inscribed angle is half the measure of the intercepted arc.

Front

How do you determine the measure of an angle formed by a tangent and a chord?

Back

The measure of the angle is equal to half the measure of the intercepted arc.

Front

What is the relationship between the angles formed by two tangents that intersect outside a circle?

Back

The angle formed is equal to half the difference of the measures of the intercepted arcs.

Front

What is the definition of a secant in relation to a circle?

Back

A secant is a line that intersects a circle at two points.

Front

What is the definition of a tangent in relation to a circle?

Back

A tangent is a line that touches a circle at exactly one point.

Front

If the measure of arc AB is 80°, what is the measure of the inscribed angle that intercepts arc AB?

Back

The measure of the inscribed angle is 40°.
