apex math definition
240 Glossary Glossary complement of a number n (1) In Everyday Mathematics, the difference between n and the next higher multiple of 10. For example, the complement of 4 is 10 - 4 = 6 and the complement of 73 is 80 - 73 = 7. (2) The difference between n and the next higher power of 10. 276 Glossary Glossary term (1) In an algebraic expression, a number or a product of a number and one or more variables. For example, in the equation 5 y+ 3 k = 8, the terms are 5 y, 3 k, and 8. The 8 is a constant term, or simply a constant, because it has no variable part. See Section 14.4: Area. A rectangle with area 1.2 cm × 2 cm = 2.4 cm 2 area model (1) A model for multiplication in which the length and width of a rectangle represent the factors, and the area of the rectangle represents the product. See Section 10.2.2: Multiplication and Division Use Classes. In geometry, an apex (Latin for 'summit, peak, tip, top, extreme end;') is the vertex which is in some sense the highest of the figure to which it belongs. 1  In an isosceles triangle, the apex is the vertex where the two sides of equal length meet, opposite the unequal third side. Coordinate Geometry. In another branch of mathematics called coordinate geometry, the points that define a line are located on the plane using their coordinates-two numbers that show where the point is positioned. For more on this, see Definition of a Line Segment (Coordinate Geometry) . If we know the coordinates of the two endpoints of a line segment, we can calculate the distance between them, and so find the length of the line segment. See Distance between two points (coordinate geometry). A Math Dictionary of Geometric Terms. Giving a child access to a Math Dictionary can alieviate much of the distress with home work and study in general. If your child gets caught on just one term, it can throw them off their entire math question. The math dictionary section bellow deals with all geometric terms starting with the letters 'A' and 'B'. As you can see we have a full geometry dictionary available here for you to explore. Simply click on the tabs to find the math definitions you are looking for. This resource, online is entirely free. However, if you would like to have a physical copy at home, off-line, for your student to have easy access to, please consider purchasing the e-book-Kindergarten to Sixth Grade Geometry Dictionary.

For example, 48% of the students in the school are boys means that, on average, 48 of every 100 children in the school are boys. See Section 9.3.4: Percents.perimeter The distance around the boundary of a 2-dimensional figure. The perimeter of a circle is called its circumference. Line Segment. Definition: A straight line which links two points without extending beyond them. Try this Adjust the line segment below by dragging an orange dot on an endpoint and see how the segment PQ behaves. Glossary 233 Glossary algebraic expression An expression that contains a variable. For example, if Maria is 2 inches taller than Joe and if the variable M represents Maria’s height, then the algebraic expression M - 2 represents Joe’s height.
It is the vertex which is in some sense the highest of the figure to which it belongs.
