Question

1. given that line n is perpendicular to line m, what are the measures of angles 1, 2, 3, and 4. n ⊥ m 90°, 90°, 180°, 180° 90°, 90°, 90°, 90° 45°, 45°, 45°, 45° 180°, 90°, 180°, 90°

Explanation:

Step1: Recall perpendicular - lines property

When two lines are perpendicular, the angles formed at their intersection are right - angles. A right - angle measures 90°.

Step2: Identify angle measures

Since line n is perpendicular to line m, angle 1, angle 2, angle 3, and angle 4 are all right - angles. So, $\angle1 = 90^{\circ}$, $\angle2 = 90^{\circ}$, $\angle3 = 90^{\circ}$, $\angle4 = 90^{\circ}$.

Answer:

$90^{\circ},90^{\circ},90^{\circ},90^{\circ}$
