How do you find the apex of a triangle?
You find the orthocenter by constructing the altitudes from the vertices in a triangle. If the triangle is obtuse, the orthocenter will fall outside the triangle. If the triangle is acute, the orthocenter will fall on the inside of the triangle. If the triangle is a right triangle, the orthocenter will lie on a vertix.
There is no such thing as a 3D triangle.
Area of a triangle is A=1/2*apothem*Permiter orA=1/2*B*HSquare is A=L*W

you do bxh-2xl
If you have the length and the width, add them together and double that sum.
It depends on what a permiter is! The perimeter is 30 units of length.
There is no such thing as a permiter. Furthermore, a 4 by 8 shape cannot be a square.

To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.
