Recall that if a quadrilateral is a rhombus, then it has four congruent sides.
FJ=2.5 cm
Practice makes perfect
Let's begin with recalling that if a quadrilateral is a rhombus, then it has four congruent sides. Since we know that FG= 2.5 centimeters, each side of this rhombus will have the length of 2.5 cm.
