Right angle and rectangle are geometric terms.
There are a few geometric terms that start with the letter G including great circle, glide, and golden ratio. Another example is golden mean.
Geometric Sequences work like this. You start out with some variable x. Your multiplication distance between terms is r. Your second term would come out to x*r, your third x*r*r, and so on. If there are n terms in the sequence, your final term will be x*r^(n-1).
One geometric term that starts with the letter J is justification. It is a definition, postulate, or theorem that is used to draw a conclusion.
You could use width and get away with it! It's worth a try.
Measure of an angle, mean and midpoint are geometric terms.

An arithmetic-geometric mean is a mean of two numbers which is the common limit of a pair of sequences, whose terms are defined by taking the arithmetic and geometric means of the previous pair of terms.
