The length of the resulting segment is the geometric mean. This can be proven by applying the Pythagorean theorem to three similar right triangles, each having as vertices the point where the perpendicular touches the semicircle and two of the three endpoints of the segments of lengths a and b. [1]
The Pythagorean Theorem deals with which relationship in a right triangle? The lengths of the legs and the length of the hypotenuse. The triangle shown is a right triangle. Create the equation to be used to find the missing lengths. (Enter the smaller leg of the triangle first.) Do not solve the equation. x^2=4^2+7^2.

- Note Lengths Summary
The whole note (or semibreve) is the simplest note to write in music as it is a notehead with no stem/tail and it is not filled in: You will often hear it said that a whole note or semibreve is worth “4 beats”. Whilst this is true in time signatures such as 4/4, 2/4 and 3/4 it is not always correct – e.g. in compound time. You need to be careful no...
A half note (or minim) is half the value of a whole note. Therefore, 2 half notes add up to the same length as one whole note. The half notes symbol is a notehead with a stem:
A quarter note (or crotchet) is a quarter of the value of a whole note. Therefore, 4 quarter notes add up to one whole note. Here is the symbol for the quarter note/crotchet. You can see that the notehead is filled in:
Eighth notes (or quavers) are half the value of a quarter note. As a result, 8 eighth notes are equivalent to 1 whole note. The symbol for an Eighth note is a quarter note with an added tail:
Sixteenth notes or semiquavers are half the value of the eight notes and so there are 16 of them in a whole note. Their symbol has 2 tails: You may also come across notes with 3 tails (hemidemisemiquavers), but these are very rare!
Here is a summary table of the note lengths and how they relate to each other: You can see that the quarter note (crotchet) has a filled notehead, a stem, but no tail. If you un-fill the notehead and remove the stem the note length gets longer. If you add more tails to the stem, the note gets progressively shorter.
The Square. the little squares in each corner mean "right angle". A square has equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
The distance around the circle. pi. The ratio of the circumference of a circle to its diameter. coordinate plane. A plane that is divided into four regions by a horizontal line called the x-axis and a vertical line called the y-axis. leg. One of the two sides of the right triangle that form the right angle. hypotenuse.

contributed. The Pythagorean theorem states that if a triangle has one right angle, then the square of the longest side, called the hypotenuse, is equal to the sum of the squares of the lengths of the two shorter sides, called the legs. So if a a and b b are the lengths of the legs, and c c is the length of the hypotenuse, then a^2+b^2=c^2 a2 ...
