Interior Angles of Triangles
2
3
Interior (inside) angles of triangles always add up to equal 180o
If we tear the corners off of a triangle
Then place them together
They will create a STRAIGHT Line
which is 180o
4
Since we know 2 angles:
180-37-63 = 80
<U = 80o
5
Since we know 2 angles, we know there is a right angle (90) and 46:
180-90-46= 44o <B = 44o
6
Since we know 2 angles:
180-118-33 = 29o <Y = 29o
