How to find the measure of an angle that is inscribed from a secant and tangent line

The video tutorial explains how to measure arcs and calculate minor arcs in a circle. It introduces inscribed angles, particularly those involving secant and tangent lines, and explains the formula for inscribed angles. The tutorial demonstrates how to apply this formula to find the measure of an angle when given the arc's measurement.

What is the measure of the minor arc if the major arc from M to N is 228 degrees?

• 180 degrees

• 360 degrees

• 228 degrees

• 132 degrees

Which type of angle is formed when a secant and a tangent intersect on a circle?

• Inscribed angle

• Exterior angle

• Interior angle

• Central angle

What is the relationship between an inscribed angle and its intercepted arc?

• The angle is equal to the arc

• The angle is unrelated to the arc

• The angle is half the arc

• The angle is twice the arc

If an inscribed angle intercepts an arc of 132 degrees, what is the measure of the angle?

• 66 degrees

• 33 degrees

• 132 degrees

• 264 degrees

What is the formula to calculate the measure of an inscribed angle?

• Measure of angle = arc + 90

• Measure of angle = 2 arc

• Measure of angle = 1/2 arc

• Measure of angle = arc
