Math Dictionary s
We at ask-math believe that educational material should be free for everyone. Please use the content of this website for in-depth understanding of the concepts. Additionally, we have created and posted videos on our youtube.
We also offer One to One / Group Tutoring sessions / Homework help for Mathematics from Grade 4th to 12th for algebra, geometry, trigonometry, pre-calculus, and calculus for US, UK, Europe, South east Asia and UAE students.
Affiliations with Schools & Educational institutions are also welcome.

SAS triangle congruence:
If there exists a one-to-one correspondence between the vertices of two triangles, such that two sides and the included angle of one triangle are congruent to the corresponding two sides and included angle of the second triangle, then the two triangles are congruent.
SAS Similarity Theorem:
If there exists a one-to-one correspondence between the vertices of two triangles, such that two pairs of corresponding sides are proportional and their included angles are congruent, then the two triangles are similar.
A triangle with no congruent sides.
Scatter Plot :
A graph of plotted points that show the relationship between two sets of data.
Secant (of a circle):
A line that intersects a circle in exactly two points.
Secant (of an angle):
For a given acute angle θ in a right triangle, secθ , is the ratio of the length of the hypotenuse to the length of the side adjacent to the acute angle θ ; the reciprocal of the cosine ratio of the given angle. See also circular function.
Sector of a circle:
A region bounded by an arc of the circle and the two radii to the endpoints of the arc.
Segment of a circle:
The region bounded by a chord and the arc subtended by that chord.
Either of the arcs of a circle determined by the endpoints of a diameter.
A 7-sided polygon (a flat shape with straight sides).
(Also called Heptagon)
A list of numbers or objects which are in a special order.(from math dictionary s)
A well-defined collection of items.
Two polygons which have the same shape but not necessarily the same size.
In a right angled triangle, the sine of an angle is:
The length of the opposite side divided by the length of the hypotenuse.
The abbreviation is sin.
Two non-coplanar lines that do not intersect.
Slant height :
Of a pyramid: The altitude of a lateral face of a pyramid.
Of a cone: The length of a line segment drawn on the lateral surface of a cone from its vertex to a point on the circle that determines its base is the slant height of the cone.
The measure of the steepness of a line; the ratio of vertical change to horizontal change.
Slope - intercept equation of a line
The equation of a line formed using its slope and its y intercept. If the coordinates of the y-intercept of the line are (0,b) and the slope is m , then the equation of the line is y = mx + b .
The locus of points in space at a given distance from a fixed point.
A rectangle with two congruent adjacent sides.
SSS triangle congruence:
If there exists a one-to-one correspondence between the vertices of two triangles, such that all three sides of one triangle are congruent to the corresponding sides of the second triangle, then the two triangles are congruent.
Statistics is the study of the collection, organization, analysis, and interpretation of data.
Straight Angle :
A straight angle changes the direction to point the opposite way. It looks like a straight line.
It measures 180° (half a revolution, or two right angles)
An object with no marked units of measure that is used for drawing straight lines.
Any quantity can be replaced by an equal quantity.
Subtraction property of equality:
If the same or equal quantities are subtracted from same or equal quantities, then the results are equal.
One after the other.
Two angles the sum of whose measures is
A number that can't be simplified to remove a square root
(or cube root etc).
The sum of the areas of all the faces or curved surfaces of a solid figure.(from math dictionary s)
Symmetric property of equality:
A property of the real numbers that states: If a = b then b = a .
