|---|---|---|---|---|---|
| Altitude of a Triangle | The perpendicular distance between a vertex of a triangle and the side opposite that vertex. Sometimes called the height of a triangle. Also, sometimes the line segment itself is referred to as this.
🗑
|
||||
| Base (of a Polygon) | It can be any side for two-dimensional figures. Typically, however, it is the bottom side, on which the polygon "sits".
🗑
|
||||
| Cubed Root | One of three identical factors of a number that is the product of those factors.
🗑
|
||||
| Diameter | The distance across a circle through its center. The line segment that includes the center and whose endpoints lie on the circle.
🗑
|
||||
| Hypotenuse | It is the side of a right triangle that is directly across from the right angle. This is also the longest side of any right triangle.
🗑
|
||||
| Leg of a Triangle | Either of the two shorter sides of a right triangle. These two sides together form the right angle in the right triangle.
🗑
|
||||
| Perfect Cubes | In arithmetic and algebra, the cube of a number n is its third power. It is the result of the number multiplying by itself three times.
🗑
|
||||
| Pythagorean Theorem | A theorem that states that in a right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs. a^2 + b^2 = c^2
🗑
|
||||
| Pythagorean Triples | A set of positive integers, a, b, and c that fit the rule a^2 + b^2 = c^2.
🗑
|
||||
| Radius | The distance from the center of a circle to any point on the circle. Also, the line segment that has the center of the circle as one endpoint and a point on the circle as the other endpoint.
🗑

| Right Triangle | A triangle with exactly one right angle.
🗑
|
||||
| Volume | The amount of space occupied by an object.
🗑
|

| Domain | It is the set of all x-coordinates of the ordered pairs of a relation or the "input" of the relation.
🗑
|
||||
| Function | A rule of two sets of numbers in which an input value from the first set has only one unique output value in the second set. In other words, a relation where each input has a unique output.
🗑
|
||||
| Range | The set of all output values or the y-values of a relation.
🗑
