Question | Answer |
angle | Two rays with the same endpoint |
polygon | A flat (two-dimensional) geometric figure that has the following characteristics: • It is made of straight line segments. • Each segment touches exactly two other segments, one at each of its endpoints. |
regular polygon | A polygon with sides that are all the same length and angles that are all the same size. |
concave polygon | A polygon that looks like it is “collapsed” or has a “dent” on one or more sides. Any polygon with an angle measuring more than 180°. |
sequence | An ordered list. For example: 2, 5, 8, 11,… is a sequence. |
line symmetry | A polygon has line symmetry (or reflection symmetry)if you can fold it in half along a line so that the two halves match exactly. |
term | An item in a sequence. For example, 8 is a term in the sequence 2, 5, 8, 11,…. |
order of operations | Parenthesis, Exponents, Multiplication/Division (whichever comes first), Addition/Subtraction (whichever comes first). |
triangle inequality | The triangle inequality states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side. For example, the triangle inequality tells you that is impossible to have a triangle with sides of |
vertex (plural: vertices) | A corner of a polygon, where two sides meet. Vertices are usually labeled with capital letters, such as A, B and C for the vertices of a triangle. |
symmetry | An object is symmetrical when one half is a mirror image of the other half. |
ambiguous | A rule is ambiguous if it can be interpreted in two or more ways. When a rule is written, it must be unambiguous. |
integers | Integers are whole numbers (positive) and their opposites (negative). |
perimeter | The perimeter of a figure, or shape, is the length of the distance around the outside of the shape. |
convention | A convention is a rule people have agreed to follow because it is helpful or convenient for everyone to do the same thing. |
endpoint | A point marking the end of a line segment. |
line segment | A line segment has a beginning and an end(called endpoints). |
line | A line is straight and extends forever in two directions |
ray | A ray starts at an endpoint and extends forever in one direction. |
prefixes | tri: 3, quad: 4, penta: 5, hexa: 6, hepta: 7, octa: 8,nona: 9, deca: 10 |
congruent | Objects having the same size and shape. |
