#### Transcript of The ABC's of 6th Grade Math

O is for Obtuse triangle
An obtuse triangle is a triangle that has one obtuse angle.
S is for Square
A square is a four sided polygon that has all congruent sides, all congruent, right angles and two sets of parallel lines.
W is for Width
F is for Face
K is for Kite
A kite is a type of quadrilateral that has two adjacent pairs of congruent lines.
In the picture shown, line AB is congruent to line BC and line AD is congruent to line DC.
A is for Area
Area is the amount of space that something takes up.
The ABC's of 6th Grade Geometry
G is for Geometry
Geometry is a section of mathematics that works with points, lines, polygons, three-dimensional shapes, etc.
L is for Length
This is a two-dimensional measurement and is usually used to find the area or perimeter of a shape. This can also be used to find the volume of a three-dimensional shape.
Width is a two-dimensional measurement usually used to find the area or the volume of a three-dimensional shape.

6th Grade Common Core Math Standards
6.G.1: Find the area of right triangles, other triangles, special quadrilaterals, and
polygons by composing into rectangles or decomposing into triangles and
other shapes; apply these techniques in the context of solving real-world
and mathematical problems.
6.G.2. Find the volume of a right rectangular prism with fractional edge lengths
by packing it with unit cubes of the appropriate unit fraction edge lengths,
and show that the volume is the same as would be found by multiplying
the edge lengths of the prism. Apply the formulas V = l w h and V = b h to
find volumes of right rectangular prisms with fractional edge lengths in the
context of solving real-world and mathematical problems.
B is for Base
The side or edge of a face of a polygon. Perpendicular to the height of the polygon.
C is for Congruent
Two or more shapes that have the same size and shape.
H is for Hexagon
M is for Measurement
Measurement is a number that shows the size or amount of something.
P is for Parallelogram
A parallelogram is a quadrilateral that has at least one pair of congruent sides and two pairs of parallel lines.
Q is for Quadrilateral
A quadrilateral is a four sided polygon. There are different types of quadrilaterals including squares, rhombuses, parallelograms, rectangles, kites and trapezoids.
T is for Trapezoid
A trapezoid is a four sided polygon that has only one set of parallel lines. You can have an isosceles trapezoid, a scalene trapezoid or a right trapezoid.
U is for Undecagon
An undecagon is a polygon that has eleven sides. You can have a regular undecagon and an irregular undecagon.
X is for X-axis
The x-axis is the horizontal axis that is on a coordinate plane.
Y is for Y-axis
The y-axis is the vertical axis on a coordinate plane.
Z is for Z-axis
Z-axis is the axis that allows for three-dimensional shapes. When compared to the x-axis and the y-axis, the z-axis is perpendicular to the coordinate plane.
V is for Volume
Volume is a measurement that measures how much space a three-dimensional shape takes up.
R is for Rhombus
A rhombus is a four sided polygon that has four congruent sides, two sets of parallel sides and two sets of congruent angles.
N is for Nonagon
A nonagon is a polygon with 9 sides.
I is for Isosceles triangle
An Isosceles triangle has two congruent sides and two congruent angles.
D is for Dimension
The first dimension can only contain points. The second dimension can contain points and lines. The third dimension can contain points, lines and three-dimensional shapes.
E is for Equilateral triangle
An equilateral triangle is a triangle that has all congruent sides and all congruent angles.
J is for Joint
A joint is when two shapes, edges or points meet.

6th Grade Common Core Math Standards
6.G.3. Draw polygons in the coordinate plane given coordinates for the vertices;
use coordinates to find the length of a side joining points with the same
first coordinate or the same second coordinate. Apply these techniques in
the context of solving real-world and mathematical problems.
6.G.4. Represent three-dimensional figures using nets made up of rectangles and
triangles, and use the nets to find the surface area of these figures. Apply
these techniques in the context of solving real-world and mathematical
problems.
