Congruent mean when a angle has the same measurement. You know when you have and vertical angle because they are right across from each other and they are congruent. A quadrilateral is a shape with 4 side and only 4 side no more no less. If i only know one angle in my intersecting quadrilateral yes i can find all the other angle because it has to equal 360 when you add all together. If i have an quadrilateral an they give me on side and that one side is 130 i can see that the other side are not going big. Next i can see one side is a right angle so the other side is 90 so now i have two side and 130+90=220. Then i subtract 220-180=40 so then 40 is the other side now we have three side. 220+40=260. Last you subtract 360-260=100 so 100 is the other side now we have four side so we found all the sides.
