do you want a straight answer or explanation?

OpenStudy (anonymous):

Straight i guess haha

OpenStudy (anonymous):

rhombus

OpenStudy (anonymous):

rectangle and square have 90 degree angles, all 4

OpenStudy (anonymous):

the middle angles are 58+58 which is not 90 meaning it has to be a rhombus and cannot be a rectangle

OpenStudy (anonymous):

or a square

OpenStudy (anonymous):

Rectangles (1) opposite sides that are parallel, (2) opposite angles that are congruent, (3) opposite sides that are congruent, (4) consecutive angles that are supplementary, and (5) diagonals that bisect each other. Rhombuses (1) Consecutive sides of a rhombus are congruent. (2) The diagonals of a rhombus bisect pairs of opposite angles. (3) The diagonals of a rhombus are perpendicular

So I take it is a rhombus
