What is a formula for surface area of triangle?

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

What A triangle is inscribed in another figure if each vertex of the triangle touches that figure true or false?

True. A triangle is said to be inscribed in another figure if each vertex of the triangle lies on the boundary of that figure. For example, a triangle inscribed in a circle has all its vertices touching the circumference of the circle.


True or false a triangle is inscribed in another figure if each vertex of the triangle lies somewhere in the interior of that figure.?

False. A triangle is inscribed in another figure if all its vertices lie on the boundary of that figure, not in the interior. For a triangle to be inscribed, it must touch the edges of the figure, such as a circle or polygon.
