If the lines are straight then it IS a triangle.
A polygon.
The measure of the amount of surface enclosed by the boundary of a figure is called its area. Area quantifies the two-dimensional space within the perimeter of a shape, such as a rectangle, circle, or triangle. It is typically expressed in square units, such as square meters or square feet.

A polygon. E.g triangles , sqares ,pentagon .
Half the base times the height A triangle is a figure that is enclosed by three connecting segments. A right triangle has one angle equal to 90 degrees. The area is 1/2 the base times the height.

A 3-sided figure is called a triangle.
A three-sided, two-dimensional polygon is called a "triangle".

The prefix 'tri' mean three or triple. An angle is formed when two lines intersect. A triangle is therefore a plane figure where three enclosed angles are formed by intersecting lines.
No. A triangle may have a 90-degree angle, but not all triangles do. The only requirement for being called a triangle is that it is a closed figure with 3 sides.No. A triangle may have a 90-degree angle, but not all triangles do.
