Hi there,im 13 yrs old in 7th grade.
I would like to answer your question.
I think the number 90 is important in Geometry because it is helpful in triangles and quadrilaterals and any other shapes (cones;trapezoids;etc.)(90 degree angles). It also represents a straight "Up and Down" from the vertex to the base or in a corner.
