|---|---|---|---|---|---|
| Alternate exterior angles | Exterior angles on alternate sides of the transversal
🗑
|
||||
| Alternate interior angles | Interior angles on alternate sides of the transversal
🗑
|
||||
| Altitude of a triangle | A straight line trough a vertex and perpendicular to a line containing the base of a triangle.
🗑
|
||||
| Angle bisector theorem | Concerned with the relative lengths of the two segments that a triangle's sideis divided into by a line that bisects the opposite angle. It equates their relative lenghts to the relative lengths of the other 2 sides of the triangle
🗑
|
||||
| Converse of angle bisector theorem | If a point is equidistant from the sides of an angle, then it is on the angle bisector.
🗑
|
||||
| Centroid of a triangle | The point where the three medians of the triangle intersect
🗑
|
||||
| Complement probability | In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur
🗑
|
||||
| Composition | Combining of distinct parts or elements to form a whole
🗑
|
||||
| Compound event | An event whose probability of occurrence depends upon the probability of occurrence of two or more independent events
🗑
|
||||
| Compression | To reduce a shape in size while retaining proportions
🗑
|
||||
| Conditional probability | The probability that an event will occur, when another event is known to occur or to have occurred
🗑
|
||||
| Conditional probability formula | The conditional probability of A given B is denoted by P(A|B) and defined by the formula P(A|B) = P(AB) P(B), provided P(B)>o.
🗑
|
||||
| Experimental probability | Ratio of the number of times the event occurs to the total number of trials
🗑
|
||||
| Frequency table | Lists items and uses tally marks to record and show the number of times they occur.
🗑
|
||||
| Fundamental counting principle | When there are m ways to do 1 thing, and n ways to do another, then there are m*n ways of doing both.
🗑
|
||||
| Glide reflection | A transformation in which a graph or geometric figure is picked up and moved to another location without any change in size or orientation
🗑
|
||||
| Glide reflectional symmetry | The symmetry that a figure has if it can be made to fit exactly onto the original when it is translated a given distance at a given direction and then reflected over a line
🗑
|
||||
| Mutually exclusive events | 2 events that cannot occur at the same time
🗑
|
||||
| n factorial | The factorial of a natural number n is the product of the positive integers less than or equal to n
🗑
|
||||
| Preimage | The original figure prior to a transformation.
🗑
|
||||
| Tessellation | A plane with identically shaped pieces that do not overlap or leave blank spaces. The pieces do not have to be oriented identically. A tessellation may use tiles of one, two, three, or any finite number of shapes
🗑
|
||||
| Theoretical probability | The likelihood of an event happening based on all the possible outcomes
🗑
|
||||
| Tree diagram | A representation of a tree structure in which the probability of each branch is written on the branch and the outcome is written at the end of the branch.
🗑
|
||||
| blank (answer blank) | blank
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
