In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram), and the diagonals have equal length. The base angles of an isosceles trapezoid are equal in measure (there are in fact two pairs of equal base angles, where one base angle is ...
The midsegment of a trapezoid is one of the two bimedians (the other bimedian divides the trapezoid into equal areas). The height (or altitude) is the perpendicular distance between the bases. In the case that the two bases have different lengths (a ≠ b), the height of a trapezoid h can be determined by the length of its four sides using the ...
These include the Calabi triangle (a triangle with three congruent inscribed squares), [11] the golden triangle and golden gnomon (two isosceles triangles whose sides and base are in the golden ratio), [12] the 80-80-20 triangle appearing in the Langley's Adventitious Angles puzzle, [13] and the 30-30-120 triangle of the triakis triangular tiling.
A parallelogram with base b and height h can be divided into a trapezoid and a right triangle, and rearranged into a rectangle, as shown in the figure to the left. This means that the area of a parallelogram is the same as that of a rectangle with the same base and height: =.
Derrick Ward Sr., a reporter at NBC4 Washington, died Tuesday from complications after a recent cardiac arrest, his family confirmed.
The extended base of a triangle (a particular case of an extended side) is the line that contains the base. When the triangle is obtuse and the base is chosen to be one of the sides adjacent to the obtuse angle, then the altitude dropped perpendicularly from the apex to the base intersects the extended base outside of the triangle.
