A triangle does not have a cross-section but the perpendicular line of a right angle triangle meets the base at 90 degrees.
The squared area of a triangle is half of its base times its perpendicular height. Or as: 0.5*base*perpendicular height = area of a triangle
The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.
any side of the triangle that is perpendicular to the height.
The altitude of a triangle is measured perpindicular to its base.
None but its apex is perpendicular to its base
Area of a triangle = 0.5*base*perpendicular height Area of a parallelogram = base*perpendicular height
'altitude' or perpendicular. If on line is the base (horizontal) line, then the line that is a 90 degrees to it is the perpendicular/altitude.
The base and height when calculating the area of a triangle are always perpendicular with each other.
Area of any triangle is: 0.5*base*perpendicular height
Area of a triangle = 0.5*base*perpendicular height
An Altitude.
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
