How do you verify perpendicular lines?
Explanation: If the slopes of two lines can be calculated, an easy way to determine whether they are perpendicular is to multiply their slopes. If the product of the slopes is , then the lines are perpendicular. In this case, the slope of the line is and the slope of the line is .
What are the perpendicular line theorems?
The linear pair perpendicular theorem states that two lines that form a pair of equal linear angles are perpendicular to each other. The perpendicular transversal theorem states that if there are two parallel lines and another line is perpendicular to one of them, then it is also perpendicular to the other one.
How do you find the perpendicular of a quadratic equation?
Let two lines be given with slopes m1 and m2.
- The lines are parallel if they have the same slope, that is. m1 = m2
- The lines are perpendicular if. m1 = -1/m2
What are the three prove to show that lines are perpendicular?
Proving Theorems about Perpendicular Lines If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line.
How do you solve perpendicular lines?
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.
What is theorem 3.2 called?
Theorem 3.2 Alternate Exterior Angles Theorem: If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent. Theorem 3.3 Consecutive Interior Angles Theorem: If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary.
Are perpendicular lines adjacent?
Definition: “Officially”, Perpendicular lines are two lines that meet to form congruent adjacent angles. Theorem 1.6.
