its either a rhombus or a square, between these choices. it cant be a rectangle since it has all the same side lengths & all right angles. can you figure it out now? if u cant just say so, & i will be happy to help :)
but its a square :)
The sides and angles of a square: The sides of a square are all congruent (the same length.) The angles of a square are all congruent (the same size and measure.) Remember that a 90 degree angle is called a "right angle." So, a square has four right angles. Opposite angles of a square are congruent. Opposite sides of a square are congruent. Opposite sides of a square are parallel. CHECK OUT http://www.coolmath.com/reference/squares.html
