NCERT DC Pandey Sunil â¦ All angles of a rectangle are equal. The length and width of the rectangle are the side lengths of the triangle; the diagonal is the hypotenuse of the triangle. Calculate the length of the diagonals. Are the two diagonals of a rectangle are equal in the measurement? to find the length of the diagonal if we know the width and height of the rectangle. The diagonals of a rectangle are equal and bisect each other. Type that value into the diagonal of a square calculator to check it yourself! 4. Diagonals are a line that is drawn inside the rectangle connecting opposite corners or vertices and hence the diagonals of a rectangle are congruent. Find the width of the rectangle and use the animation or the calculator above to verify your answer. The diagonals of a square are the line segments that link opposite vertices â¦ In the figure above, click 'reset'. The diagonals have the following properties: In the figure above, click 'reset'. Books. A diagonal divides a rectangle into two right triangles. Just know we discussed that for a rectangle there will be two diagonals. Ex 8.1, 2 If the diagonals of a parallelogram are equal, then show that it is a rectangle.
