maths in hindi language-what a challenge

taught underpriviledged kids for 4 weeks (during thesis writing, 2 years ago) geometry in hindi language-imagine concepts of  trikon (triangle), kon (angle), parallel lines, corresponding angles...what a challenge! Whew! girl students-who otherwise take care of their siblings, and domestic chores in addition to going to  school... i wonder how such mathematical concepts would help them practically in life..left teaching and got back to writing my thesis..
