Question

what statement is true about perpendicular lines?

Answer 1

A true statement about perpendicular lines is that they intersect at a right angle, which measures 90 degrees. In a Cartesian coordinate system, if two lines have slopes \(m_1\) and \(m_2\), they are perpendicular if the product of their slopes is -1, or mathematically, \(m_1 \times m_2 = -1\).
