`1.  Side (base) of a right trapezoid if you know other base and midline of a trapezoid  `  , -  bases - midline

Calculate the side of a trapezoid if given middle line and other base  ( a b  ) :  `2.  Sides (bases) of a right trapezoid if you know lateral sides, angle at the base and other base  `  , -  bases - lateral side = height - lateral side -  angle  at the base

Calculate the base of a trapezoid if given lateral sides, angle at the base and other base  ( a b  ) :      `3.  Sides (bases) of a right trapezoid if you know diagonals, lateral side (height) and angle between the diagonals  `  , -  bases - lateral side = height , -  diagonals , -  angles between the diagonals

Calculate the side (base) of a trapezoid if given diagonals, lateral side (height) and angle between the diagonals ( a b  ) :  * It is true in this case: `4.  Sides (bases) of a right trapezoid if you know area of a trapezoid, lateral side (height) and other base  `  , -  bases - lateral side = height -  height -  area

Calculate the side (base) of a trapezoid if given area of a trapezoid, lateral side (height) and other base ( a b  ) :  * It is true in this case:
