WebIn elementary geometry, two geometric objects are perpendicular if their intersection forms right angles (angles that are 90 degrees or π/2 radians wide) at the point of intersection called a foot.The condition of perpendicularity may be represented graphically using the perpendicular symbol, .Perpendicular intersections can happen between two lines (or two … WebThe perpendicular lines are two lines that intersect each other and the angle formed between the two lines should be equal to 90 degrees (right … WebA perpendicular is a straight line that makes an angle of 90 ° with another line. 90 ° is also called a right angle and is marked by a little square between two perpendicular lines as shown in the figure given below. Here, the two lines intersect at a right angle, and hence, are said to be perpendicular to each other. Now, let us look at the examples of lines that are … thea tillemans driefuis
