astro.com - draw up your chart - look over the circular natal chart wheel - if it is still hard to tell anything - click to view additional tables - on the right it will tell you exactly where each cusp is in the sign that it falls, as well as the planets of rule (left), and your general aspect grid (bottom).
(these are my cusps as viewed within additional tables at astro.com)
(sometimes a person will not have all 12 signs ruling a house - they may have them intercepted; sometimes the same sign will rule two houses.) ^^;
You will need an accurate birth time to draw up house placement (cusps).
My 1st house is ruled by Mercury (because it is Virgo); Mercury is in my 4th house under Capricorn, 4th house has Sagittarius on the cusp though, as you can see here, Sagittarius is ruled by Jupiter, which is domicile for me, meaning it is in its own sign. Mercury also rules my 10th house (Gemini) - planets falling in their traditional houses are also given exaltation, domicile, or debilitated statuses too~ I have 5th house cusp Capricorn Sun - the Sun is in its natural house, domicile, while Jupiter is in exalt by house falling within Cancer's natural/traditional house.
Recognizing house rulership is very beneficial to determining more accurately, (more clearly defining) - the influence and area projected/emphasized by aspects and placements within our chart, and to determine the effects of transits, and to see more precisely how compatible we are with others/things. All of these charts and more are available within the astro.com site~! ^^
Hope this helps a bit!
