- Lines AB and CD intersect at O. If angle AOC+ angle BOE= 70 degree and angle BOD = 40 degree , find angle BOE and reflex angle COE
- what does subtend mean?
- A graph may be defined as a set of points connected by lines called edges. Every edge connects a pair of points. Thus a triangle with 3 edge and 3 points. The degree of a point is the number of the edges connected to it. For example, a triangle is a graph with 3 points of degree 2 each. Consider a graph with 12 points. It is possible to reach from any other point through a sequence of edges. The number of edges, e, in the graph must satisfy the condition:- a) 11 ≤ e ≤ 66 b) 11 ≤ e ≤ 65 c) 10 ≤ e ≤ 66 d) 0 ≤ e ≤ 11
- Prove that if a ray stands on a line, then the bisectors of the two adjacent angles so formed are perpendicular to each other.
- Given that each of the angles AOC and AOB is a right angle. Show that BOC is a straight line.
