- In O, chord AB chord CD. Radius OE is perpendicular to AB and CD at points M and N, respectively. If OE=13, AB=24, and CD=10, then the distance from O to CD is greater than the distance from O to AB. Determine how much farther chord CD is from center O than chord AB is from center O; that is, find MN.arrow_forwardIn Exercises 19 to 22, classify each statement as true or false. In Exercises 19 to 20, recall that the symbol means is a subset of. Where Q=quadrilaterals and P=polygons, QP.arrow_forwardIn Exercises 31 to 33, give a formal proof for each theorem.
