Pronunciation: [pˌɜːpəndˈɪkjʊlə dˈɪstəns] (IPA) 
Perpendicular distance is a mathematical term used to describe a line that is drawn at a ninety-degree angle to a point. There are many synonyms for this term, including orthogonal distance, normal distance, shortest distance, and altitude. Orthogonal distance refers to a distance that is measured along a line that is perpendicular to the object being measured. Normal distance is used to describe a distance that is perpendicular to a plane. Shortest distance is a term used to describe the distance between two lines or objects that is the shortest possible distance. Altitude is the perpendicular distance between a point and a plane. All of these terms refer to the same type of distance, but each has its own unique application in different areas of math and science.
