No.
In a trapezium, there are two perpendicular lines. These perpendicular lines are the diagonals of the trapezium. The diagonals of a trapezium are the line segments that connect non-adjacent vertices of the trapezium and intersect each other at a right angle.
No
No but the diagonals of a square, rhombus and a kite are perpendicular to each other
If the diagonals are congruent and are perpendicular bisectors of each other then the parallelogram is a square. If the diagonals are not congruent but are perpendicular bisectors of each other then the figure would be a rhombus.
No but its diagonals are perpendicular to each other.
No
No.
No, the diagonals of an isosceles trapezium do not bisect each other. In an isosceles trapezium, while the non-parallel sides are equal in length, the diagonals are not equal and do not intersect at their midpoints. Instead, they cross each other at an angle, creating two pairs of triangles that are congruent but do not share their midpoints.
It has two diagonals, and they are perpendicular to each other.
It is a rhombus whose diagonals are perpendicular and meeting each other at right angles.
No but its diagonals are perpendicular to each other
If you are talking about the diagonals of a quadrilateral, the only quadrilateral that have diagonals that are perpendicular and bisect each other is a square, because a rectangle has bisecting diagonals, while a rhombus has perpendicular diagonals. And a square fits in both of these categories.
