AB and CD intersect at point as shown below. Select the most precise and correct statement about perpendicular lines from among those that are given.
Choose 1
AB is
is perpendicular to
CD if the two lines intersect such that the measure of ZAOD
equals the measure of ZBOC.
AB is perpendicular to CD if the two lines never meet.
AB is perpendicular to
CDI
if the two lines intersect such that ZAOD is a right angle.
A1

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

i think the answer would be c
