Question

the figure shows three intersecting lines. lines g and h are perpendicular.
how are ∠1 and ∠2 related?
complete the equation.
m∠1 + m∠2 = □

Explanation:

Step1: Recall the definition of perpendicular lines

Since lines \(g\) and \(h\) are perpendicular, the angle between them is \(90^{\circ}\).

Step2: Analyze the relationship between \(\angle1\) and \(\angle2\)

The sum of \(\angle1\) and \(\angle2\) forms the right - angle between lines \(g\) and \(h\). So \(m\angle1 + m\angle2=90^{\circ}\)

Answer:

\(90\)
