Only when it is in the form of a right angle triangle that it will have perpendicular lines that meet at 90 degrees.
A shape with three and only three sides is a triangle, but it is not possible for a triangle to have three perpendicular sides.
Any polygonal shape, other than a triangle can have perpendicular lines.
triangle.
equilateral triangle
Not necessarily. It is a plane shape which could be horizontal.
A right angled triangle is an example of a shape with exactly 2 perpendicular sides.
A shape with one pair of perpendicular lines is a right-angled triangle. In this triangle, one of the angles measures 90 degrees, which creates the perpendicular intersection of the two lines that form the legs of the triangle. This characteristic defines the right triangle and distinguishes it from other types of triangles.
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
A right angle triangle.
Yes its perpendicular height or altitude is sometimes calculated out side the triangle depending on its shape.
Any shape, other than a triangle can have a pair of perpendicular sides.
A right angled triangle.
