| a theorem you prove before the big theorem to make proving the big theorem easier is called a ? | lemma |
| If a line is perpendicular to a plane, then it is ? to every line in the plane that passes through the ? | perpendicular / point of intersection |
| the point of intersection of a line and a plane is called the ? | foot |
| a line is perpendicular to a plnae if and only if it is perpendicular to every ? that passes through the foot | line |
| if B and C are each equidistant from P and Q then every point between B and C is ? from P and Q | equidistant |
| State the Basic Theorem on Perpendicularity | If a line is perpendicular to each of 2 intersecting lines at their point of intersection then it is perpendicular to the plane that contains them |
| If a line and a plane are perpendicular, then the plane contains ? perpendicular to the given line at its point of intersection with the plane | every line |
| through a given point of a given line, there passes ? plane perpendicular to the given line | exactly 1 |
