Uhly sa používajú všade okolo nás - od stavby domov... Show more











Uhol je časť roviny ohraničená dvoma polpriamkami s rovnakým začiatkom. Každý uhol má vrchol (spoločný bod) a ramená (tie dve polpriamky).
Meráme uhly v stupňoch pomocou uhlomera. Celý kruh má 360°, čo je super užitočné vedieť!
Tip: Vždy si nakresli obrázek - pomôže ti lepšie pochopiť, o ktoré uhly ide.

Podľa veľkosti rozdeľujeme uhly na šesť typov:
Ostrý uhol (0° až 90°) vyzerá ako špic. Pravý uhol má presne 90° a vyzerá ako roh štvorca - značíme ho oblúčikom s bodkou. Tupý uhol (90° až 180°) je "otvorenejší" ako pravý.
Priamy uhol má 180° a je vlastne priamka. Vypuklý uhol (180° až 360°) je ten "väčší" uhol. Plný uhol má 360° - je to celá otočka dokola.
Pamätaj si: Pravý uhol = 90°, priamy uhol = 180°, plný uhol = 360°

Susedné uhly majú spoločný vrchol a jedno spoločné rameno. Ak sú na priamke, ich súčet je vždy 180°. To znamená: α + β = 180°.
Vrcholové uhly vzniknú, keď sa pretnú dve priamky. Ležia oproti sebe cez spoločný vrchol a sú vždy rovnaké. Ak je jeden vrcholový uhol 60°, druhý je tiež 60°.
Skvelé: Tieto pravidlá ti pomôžu vypočítať neznáme uhly aj bez uhlomera!

Keď priečka pretína dve rovnobežné priamky, vznikne až 8 uhlov! Tu platia špeciálne pravidlá, ale len ak sú priamky naozaj rovnobežné.
Súhlasné uhly ležia na rovnakej strane priečky v rovnakej polohe a sú rovnaké. Napríklad oba "hore vľavo" pri každom priesečníku.
Striedavé uhly ležia na opačných stranách priečky. Môžu byť vnútorné (medzi rovnobežkami) alebo vonkajšie (mimo rovnobežiek). Ak sú priamky rovnobežné, striedavé uhly sú rovnaké.
Pozor: Pravidlá pre súhlasné a striedavé uhly platia LEN pri rovnobežných priamkach!

Pri riešení príkladov s uhlami postupuj systematicky. Najprv si nakresli obrázok a označ známe uhly.
Ak máš pretínajúce sa priamky s jedným uhlom 50°, použiješ pravidlá: vrcholový uhol je tiež 50°, susedné uhly sú 180° - 50° = 130°.
Pri rovnobežkách s priečkou si postupne vypočítaj všetky uhly pomocou pravidiel pre súhlasné a striedavé uhly. Vždy si skontroluj výsledok - susedné uhly musia dať spolu 180°.
Tajomstvo úspechu: Hľadaj priamky! Ak vidíš priamku, uhly na nej majú spolu vždy 180°.

Pre test si zapamätaj: ostrý uhol (<90°), pravý uhol (=90°), tupý uhol (90°-180°), priamy uhol (=180°).
Susedné uhly na priamke: súčet = 180°. Vrcholové uhly: vždy rovnaké. Súhlasné uhly pri rovnobežkách: rovnaké. Striedavé uhly pri rovnobežkách: rovnaké.
Nezabudni správne značiť pravý uhol oblúčikom s bodkou a rovnobežné priamky šípkami.
Kľúč k úspechu: Vždy skontroluj, či sú priamky rovnobežné, pred použitím pravidiel!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
