Also, known as the height of the triangle, the altitude makes a right-angle triangle with the base. Below is an image that shows a triangle’s altitude. What is the Use of Altitude of a Triangle?
WebA triangle is a closed 2-dimensional shape with three sides. There are different names for the types of triangles. Based on the length of the sides, there are three types of triangles: scalene, isosceles and equilateral triangles. A triangle’s name also depends on the measure of its interior angle: acute (if all angles are less than 90 ... A right triangle (American English) or right-angled triangle (British), or more formally an orthogonal triangle, formerly called a rectangled triangle (Ancient Greek: ὀρθόσγωνία, lit. 'upright angle'), is a triangle in which one angle is a right angle (that is, a 90-degree angle), i.e., in which two sides are perpendicular. … See more Area As with any triangle, the area is equal to one half the base multiplied by the corresponding height.
