magnitudeof rotationIn a rotation, the amount that the preimage is turned about the facility ofrotation, measured in levels from -180 (clockwise) to 180 (counterclockwise),+/- m
Rotations,which room sometimes dubbed turns, can additionally have magnitudes outsidethe variety of -180 to 180 degrees, such together 720 levels or-500 degrees. The point you desire to psychic is that you space goingaround in a circle, and every circle has only 360 degrees. Therefore a rotationof -500 levels is really just one complete, clockwise, revolutionof -360 and also -140 levels more.

magnitudeof dimension transformationIn a size change, the factor whereby the length of the preimage is changed,A'B'/AB , whereby A' and also B' are the photos of A and B under the transformation.Also dubbed a size change factor or scale factor of size transformation.

You are watching: Math words that start with m

The magnitudeof this size change is two, because AB=5 units and A'B'=10.The lengths ~ above the photo A'B'C' are all 2 times larger than top top thepreimage ABC.

magnitudeof translationThe distance between any suggest and its image.

major arcAB of one O Thepoints of one O that are on or in the exterior of angle AOB.

NOTE:Three letter are provided to identify significant arcs.

mappingAn operation on a geometric figure whereby each allude gives increase to aunique image. A correspondence in between two to adjust of point out such the eachpoint in the preimage set has a distinctive image, and each allude in the imageset has precisely one preimage. Likewise called a transformation.

matrixA rectangular range of rows and columns.


meanA number thatdescribes a collection of other numbers. You get a mean, or average, asit is generally called, by taking the amount of the numbers being examinedand then splitting that sum by how countless numbers to be added.

For example: come findthe mean, or average, the 10, 9, 8, and also 5 this is what you would certainly do:


means In the proportiona/b = c/d, the numbers b and c.


Proportions provided to alwaysbe written v colons top top a right line together you check out at the topof ours example. The word "means" supposed "middle",thus the two numbers in the middle were referred to as the means. That madeperfect sense to those historical folks, yet people this particular day oftenwonder why b and also c are dubbed the method because todaywe commonly write proportions together equal fractions with a horizontalfraction bar.

*NOTE:a and also d are called the extremes. This is due to the fact that "extremes"meant "outside" and also the a and also d space on theouter sides of the horizontally written proportion.

means-extremespropertyIn any kind of proportion, the product the the means equals the product of theextremes. Some world learn this as "cross commodities are equalin any kind of proportion."


measureThe dimension or lot of something, normally in a mechanism of units.

medial triangleThe union of segment that join the midpoints the the political parties of a triangle.


median ofa triangle Thesegment connecting a vertex of the triangle come the midpoint of the oppositeside.


Herewe see every one of the medians of triangle CEN. The spot whereby they intersect,pt R, is called the facility of gravity, and also is a perfect balance pointfor the triangle. You deserve to prove this by cutting the end the triangle andbalancing the on the guideline of a pin straight at allude R.

mixednumeral Asymbol consisting of a entirety number through a portion next to it, when writtenlike this it means the numbers are being added.


mixednumber Anumber written as a combined numeral.

modeThe number which appears most often in a data set. The setting of the followingdata collection is 6 : 15, 6, 2, 6, 42, 6.

It is feasible to have actually morethan one setting as in the collection 1, 1, 3, 12, 4, 4. The is feasible to haveno setting if no values appear much more than as soon as as in the collection 1, 2, 3, 4.

Mult-RecProperty of division Forany number a, and also b, with b no equal come 0:a/b = a times 1/b. In words, to division by a number is the sameas multiply by that is reciprocal.

Ex: To divide by 2gives the very same answer together multiplying through 1/2. 24 divided by 2 = 12 and24 time 1/2 = 12.
