Welcome! Today we'll learn how to draw a 45 degree angle. A 45 degree angle is exactly half of a square corner. Think of it like cutting a square corner right down the middle!
Let's start with step one. Draw a straight line going across your paper. This line can go from left to right. Make it nice and straight - this will be one side of our 45 degree angle.
Now for step two! From one end of your straight line, draw another line going straight up. This makes what we call a square corner, just like the corner of a square or rectangle. This square corner is exactly 90 degrees.
Here's the magic step! From the same corner point, draw a line that goes right through the middle of your square corner. This diagonal line splits the 90 degree angle exactly in half, creating two perfect 45 degree angles!
Congratulations! You've successfully drawn a 45 degree angle! You can see that your diagonal line creates two equal 45 degree angles. Remember, a 45 degree angle is always half of a square corner. Now you can draw 45 degree angles anytime you need them!
