2.2 Comparing Angles
Roofs can have different steeps and have different slopes. A steeper roof slopes with a greater angle than a roof which has less steep. 
Large Roof Angle 
Small Roof Angle 




Equal Angles
If angles are equal then they are marked with one or more lines. 

The figure shows a parallelogram where the opposite sides are parallel. The opposite angles are then also equal.
ΛA = ΛC and ΛB = ΛD. 


Which of these angles are bigger? 

They are equal.
