What is the measure of the angle formed by 2 chords intersecting within a circle if the opposite arcs they intercept are 90 and 130?
15pi. after you add.
How are lengths of intersecting chords related?
If two chords intersect within a circle, the product of the two segments of one chord equals the product of the two segments of the other chord. In short, if two chords intersect in a circle, their length is equal.
Are chords diameters?
By definition, diameters are lines that reach all the way across the circle, crossing the middle point. The definition of a chord is a line segment that stretches across a circle intersecting at two points that does not cross the middle point. Chords are not diameters, for the property that makes a line segment a diameter is the intersection with the middle point. If the line segment is a diameter, then it automatically means that it is not a chord, for in essence, they are opposite.
Why can't all chords diameters?
The only chords that are diameters are the chords that go through the center of the circle. All of the other chords are shorter.
What is the opposite of chord?
The opposite of consonance chords are dissonance chords.
The measure of an angle formed by intersecting chords is of the sum of the measures of the intercepted arcs?
It is the measure of half the intercepted arc.

Chords ab and CD of circle o intersect inside the circle find the measure of the acute angle formed if arc ac is 42 and arc db is 94?
If two chords intersect inside a circle, the acute angle they form is one half of the sum of the arcs intercepted by its sides and by the vertical angle SO... The acute angle will be one half the sum of the two arcs. So it is 1/2(42+94)=68 degrees.
How do you work out angles in a semi-circle?
An inscribed angle is an angle formed by two chords in a circle which have a common endpoint. This common endpoint forms the vertex of the inscribed angle.The other two endpoints define an intercepted arc on the circle Any angle inscribed in a semi-circle is a right angle. The proof is simply that the intercepted arc is 180 so the angle must be half of that or 90 degrees.
What are some alternative chords that can be used in place of traditional chords in a song?
Some alternative chords that can be used in place of traditional chords in a song include suspended chords, augmented chords, diminished chords, and extended chords. These alternative chords can add unique and interesting sounds to the music.
What are the different types of chords that can be formed in a major scale?
The different types of chords that can be formed in a major scale are major chords, minor chords, diminished chords, and augmented chords.
Which of the following was NOT characteristic of Impressionist music?
