# Unit 10 Circles Homework 5 Inscribed Angles Answers

## What is an Inscribed Angle? An inscribed angle is an angle created by two chords that intersect inside a circle. Its vertex is the center of the circle and its sides are the chords. When two inscribed angles intersect, they form a straight line that passes through the center of the circle. Inscribed angles are used to measure angles in circles and to calculate the lengths of arcs.

## Inscribed Angle Theorems The two most important theorems related to inscribed angles are the Central Angle Theorem and the Inscribed Angle Theorem. The Central Angle Theorem states that angles created by two chords that intersect inside a circle are equal to half the measure of the arc subtended by the angle. The Inscribed Angle Theorem states that an angle inscribed in a circle is one-half the measure of its intercepted arc.

## Inscribed Angle Homework Unit 10 circles homework 5 inscribed angles answers are based on the theorems described above. The homework involves measuring the angles of circles using inscribed angles and calculating the length of arcs. To complete the homework, students must understand the two theorems and how to apply them to calculate angles and arcs.

## Tips for Solving Inscribed Angle Problems When solving inscribed angle problems, it is important to remember that the measure of the angle is equal to half the measure of the arc it intercepts. This means that the measure of the angle can be found by dividing the measure of the arc by two. Additionally, it is important to remember that two inscribed angles that intersect create a straight line that passes through the center of the circle.
