Down: 1) We use a little circle ° following the number to mean degrees.3)  Two angles are ________ when they have a common side and a common vertex (corner point), and don't overlap.4) The graph of y = 2x+1 is a straight line 7)  The little square in the corner tells us it is a right angled triangle (I also put 90°, but you don't need to!) Across: 2) When two angles add to 90°,5)  Opposite angles. The interesting thing here is that vertically opposite angles are equal:6) When the two angles add to 180°,8) When a line is split into 2 and we know one angle we can always find other measures.
