| Name four things that Two Capital Letters printed together can mean? | Two Capital Letters together can mean the following: 1) to represent the name of the line; 2) to represent the name of a ray; 3) to represent the name of a segament; 4) to represent the length of a line segament. |
| Name four things that Three Capital Letters printed together can mean? | Three Capital Letters together can mean the following: 1) to represent an angle; 2) to represent a triangle; 3) to represent a major arc; 4) to represent a plane. |
| Define: Line | A "line" goes on forever in both directions |
| Define: Vertix | The "vertex" is the point at where the two rays of a angle intersect. |
In angle | The vertex is point "R". | |
| A "plane" must be made up of at least how many points. | A "plane" must be made up of at least three(3) points. |
| Define: Arc | An "arc" is a portion of the edge of a circle. |
| A "triangle" must be made up of at least how many points. | A "triangle" must be made up of at least three(3) points. |
| Define: Acute angle | An Angle that is less then 90 Degrees (0-89 degrees) |
| Define: Right angle | An angles that is exactly and only 90 degress |
| Define: Obtuse angle | An Angle more than 90 degrees and less than 180 degress. |
| Define: Straight Angle | A straight line that measures exactly and only 180 degrees |
| Define: Angle bisector | A line that divides an angle into two equal parts. |
| Define: Exterior of an angle | The "Exterior of an angle" is the area outside of an angle. |
| Define: Interior of an angle | The "Interior of an angle" is the area inside of an angle. |
| Define: Supplementary angles | Supplementary angles are two angles that add up to 180 degrees. |
| Define: Complementary angles | Complementary angles are two angles that add up to 90 degrees. |
| Define: Adjacent angles | Adjacent angles share "one side" together. |
| Define: Linear pair | A Linear pair are two angles that share the same line. |
| Define: Vertical angles (Oppose angles) | Vertical angles (Opposite angles) are two angles oppose each other when two lines intersect - vertical or opposite angles are congruent (equal to each other). |
| Define: Congruent | Congruent means equal to each other. |
