Write a paragraph proof of theorem 3-8: in a plane, if two lines are perpendicular to the same line, then they are parallel to each other. · given colon r perpendicular s, t perpendicular s · prove colon r parallel t · a diagram is shown of line r and line t with line s intersecting both line r and line t. · four angles are formed at the intersection of line r and line s. angle 1 is in the top left position, angle 2 in the top right position, angle 3 in the bottom left position, and angle 4 in the bottom right position. · four angles are formed at the intersection of line t and line s. angle 5 is in the top left position, angle 6 in the top right position, angle 7 in the bottom left position, and angle 8 in the bottom right position.

Ratio testwe can show it converges absolutely lim          |d{n+1}/10^(n+1)|/|d{n}/10^n|n->inf=  "          |d{n+1}/10^n*10|*|10^n/d{n}|=  "          1/10*|d{n+1}/d{n}|the digits can range form 0 to 9the biggest number that can be in that absolute value thing is 9/1so1/10*9=9/10<1so it converges absolutely
