Question

prove that diagonals of a square divides the square into two congruent triangles . also prove that the diagonals of a square bisect its vertex angles. ​

Answer 1

mark me as brainliest

Step-by-step explanation:

Let ABCD be the square and line AC be its diagonal. We know, in a square all sides are equal and all the angles are right angled.

So, in ABC and ACD,

AB=CD

angle ABC= angle ACD

AD=BC

So, by SAS congurency both the triangles are equal.
