Step 1
In the questions.
1a,b)
i)AB represents a line segment. It has both the end points
ii)-->AB represents a ray.as it has one end point
iii)<--> AB represents a line with no end points.
c)No they are not equal as they have different directions.
Step 2
d)No it does not tessellate.
e) If the figure is same on all sides, it will not fit together. Hence does not tessellate.
f)Diagonal or Perpendicular bisector.
g)Vertically opposite angles.
h) Yes the sine rule is applicable for non - right angled triangles.
