If two chords intersect inside a circle, the angles formed are called inscribed angle

Idon't necessarily know if this was a question formatted to be answered in a true or false format, or if this was an answer that you want to be check as true or false. but i guess whatever answer applies to both. the answer is true because  if one attitude is ninety ranges, then its opposite attitude is likewise ninety ranges. apart from, the sum of the attitude and its adjoining attitude equals one hundred eighty ranges, so all 4 angles are ninety ranges.hope this : )
