A flat shape with 4 straight sides where opposite sides are parallel,opposite sides are equal in length, and opposite angles are equal is called Parallelogram.
Here in above picture, Parallelogram NBPJ ~ Parallelogram XHLD i.e. both are similar as all the sides and all the angles are congruent. . Since, parallelograms are similar every corresponding angle or side is also similar to other parallelogram . ∴ ∠J is similar to ∠D as angle D is corresponding to angle J in both parallelograms { ∠J ⇔ ∠D }. Side NB is corresponding to side XH , so NB ⇔XH. ∠P is corresponding to ∠L , ∴ ∠P ⇔ ∠L. Side JN corresponds to Side DX , so JN ⇔ DX.
There are 20 girls on the team so theres your first number then you add the girls and boys to get the total number of players (46) and write out your ratio
