Brb, I'm getting something to draw with

I started this knowing hexagon's angles total 720 degrees

OpenStudy (littlebird):

So each individual angle is 120 degrees

OpenStudy (littlebird):

Angle 3 is half of one of the hexagons corners, so it is 60 degrees

OpenStudy (littlebird):

Angle 3 is part of a right triangle, and with it being 60 degrees....

OpenStudy (littlebird):

We have a 30-60-90 triangle (180 degrees in a triangle)

OpenStudy (littlebird):

In other words, angle 2 is 30 degrees.

OpenStudy (littlebird):

OpenStudy (littlebird):

Angle 2 is half of the top angle in the triangle highlighted in black

OpenStudy (littlebird):

So the angle at the top of the black traingle is 60 degrees

OpenStudy (littlebird):

Hexagons are consistent, so all of its angles around the center are the same size

OpenStudy (littlebird):

Angle 1 is 60 degrees

OpenStudy (littlebird):

One day this thought process will take a few seconds

OpenStudy (anonymous):

So therefore angle 1 equals to 60 degrees?

OpenStudy (littlebird):

Yes
