Question

prove that rombus with one angle 90° is square​

Answer 1

Answer:

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)let the other 2 angles be x

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)let the other 2 angles be xnow

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)let the other 2 angles be xnowx+x+90+90=360

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)let the other 2 angles be xnowx+x+90+90=3602x=180

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)let the other 2 angles be xnowx+x+90+90=3602x=180x=90

As we know that opposite angles of the rhombus are equal therefore 2 angles are 90...( i.e. the given one and opposite to it)let the other 2 angles be xnowx+x+90+90=3602x=180x=90therefore the required angles of the rhombus are 90,90,90,90 and we know that all the sides of the rhombus are equal...hence it is a square..
