l and m are two lines perpendicular to each other. What is the measure...
Explanation:

When two lines are perpendicular to each other, they form a right angle. A right angle measures 90 degrees. Therefore, the measure of the angle between the two lines is 90 degrees.

Proof:

To prove that the angle between two perpendicular lines is 90 degrees, we can use the concept of alternate angles and the fact that the sum of angles in a straight line is 180 degrees.

1. Let's assume that line L is perpendicular to line M.
2. We can draw a transversal line that intersects both L and M.
3. When a transversal intersects two lines, it creates a pair of alternate angles.
4. Since L and M are perpendicular, the alternate angles created by the transversal will be congruent (equal in measure).
5. Let's label the alternate angles as angle 1 and angle 2.
6. Now, let's consider the straight line formed by line L, the transversal, and line M.
7. The sum of angles in a straight line is 180 degrees.
8. Therefore, angle 1 + angle 2 = 180 degrees.
9. Since angle 1 and angle 2 are congruent, we can rewrite the equation as 2 * angle 1 = 180 degrees.
10. Solving for angle 1, we get angle 1 = 90 degrees.
11. Hence, the measure of the angle between the perpendicular lines L and M is 90 degrees.

Conclusion:

The measure of the angle between two lines perpendicular to each other is always 90 degrees. Therefore, the correct answer is option D) 90.
