I don't know how to sum geometrical figures. I suppose you could count it: one! One trapezoid! Ah ah ah ah ah.
The sum of the interior angles of any convex four-sided polygon is 360 degrees.
The some of the exterior angles of any convex polygon (no matter how many sides it has) is 360 degrees.
The sum of the four interior angles of a trapezoid is 360 degrees.
The sum of the 4 interior angles of a trapezoid add up to 360 degrees.
The sum of all the interior angles of any trapezoid is 360 degrees.
Area of a trapezoid: 0.5*(sum of its parallel sides)*height
Yes.
The sum of the four interior angles of a trapezoid is 360 degrees.
A trapezoid (not tapezoid!) is a plane shape. It has no quantity associated with it so there is no "sum of a trapezoid".
The sum of the 4 interior angles of a trapezoid add up to 360 degrees.
The sum of all the interior angles of any trapezoid is 360 degrees.
Area of a trapezoid: 0.5*(sum of its parallel sides)*height
Area of a trapezoid = 0.5*(sum of parallel side)*height
Area of a trapezoid = 0.5*(sum of parallel sides)*height
Area of a trapezoid: 0.5*(sum of parallel sides)*height
Yes.
the sum of the angles of a trapizoid equal 360 degrees.
The 4 interior angles of a trapezoid add up to 360 degrees
The 4 interior angles of a trapezoid add up to 360 degrees
