Detailed explanation-1: -Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Detailed explanation-2: -If two sides of two adjacent acute angles are perpendicular, then the angles are complementary. If two lines are perpendicular, then they intersect to form four right angles. If two lines are perpendicular, then they intersect to form four right angles.
Detailed explanation-3: -Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines.
Detailed explanation-4: -Definition: “Officially”, Perpendicular lines are two lines that meet to form congruent adjacent angles. Theorem 1.6. 1: If two lines are perpendicular, then they meet to form right angles.
Detailed explanation-5: -Hence we can see that, when two lines are perpendicular to each other, they form 4 right angles (90 degrees).
