Answer 1

Answer:Answer:ABCD is a quadrilateral in which all 4 sides are equal.

Yes

Any quadrilateral having all 4 sides equal is called a rhombus.

However, in a rhombus the measures of the angles can be anything other than 90deg.

Since 1 angle of the quad ABCD is 90deg, then remaining will also be 90deg because the sides are of equal lengths.

Therefore it is a square
