Answer 1

To prove-Diagonals of the square bisects the square in four congruent triangles ....
Proof- Quadrilateral ABCD us a square.
we know that
Diagonals of the square are yhe perpendicular bisector of each other.
Means diagonals AD and BC are the perpendicular bisectOrs of each other.
Then we also know that the diagonals of square bisects each other.
Therefore, the diagonals are divided as AO,OD,OB and OC....
Perpendicular bisector means each angle is of 90 degree....
Therefore Angle AOC ,Angle BOD,AngleCOD and Angle AOB are the right angles.
So,Triangle AOC=Triangle BOD=TriangleCOD=Triangle AOB....
Therefore we can say that diagonals of square bisects into four congruent triangles.
Hence proved.
