The kanji and the word are exactly the same. That means they share meanings as well.
But this word has two different meanings and each one has its own reading. You should make sure you don't mix them up. The first one is the reading you learned with the kanji. かく means angle.
The second reading (かど), is something you haven't learned, and it means corner. Just picture a deck of cards (かど). Now take one card at a time and fold them to make a corner. Now tape those cards into all the corners of your house. Why? Because it's artsy!
Please turn left at the next corner.
