It is: number of sides -2 = number of triangles
yes, a triangle is a closed figure
No- a triangle is a plane figure, not a solid.
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
If the figure is a rectangle, the area is 60. If the figure is a triangle, the area is 30.

A right angle is a plane figure and cannot have a volume.
An equilateral triangle
true
If you know how to find the area of a triangle do the same thing and you will get the same answer.
If a figure has four sides, then it is a quadrilateral; it cannot be a triangle.
well yes, obviously. A triangle constitutes of three points, and you can always find a plane that traverses those three points.
It is a triangle
