Question

which point is not a vertex of the triangle?
(A)Z
(B)A
(C)B
(D)C​

Answer 1

Answer:

A is not a vertex of triangle

Answer 2

In the given diagram, the point which is not a vertex of the triangle is (B) A.

Explanation:

• We know, A Triangle is a polygon with three sides, three vertices and three angles.
• Vertex of a triangle is defined as the point where any two sides of a triangle meet.
• In the given figure,

1. Point B is a vertex since Sides BC and BZ meet at point B.
2. Point C is a vertex since Sides BC and CZ meet at point C.
3. Point Z is a vertex since Sides CZ and BZ meet at point Z.
4. But, Point A is not a vertex since no side of  the triangle meets there.

Hence, According to the given diagram, the point which is not a vertex of the triangle is (B) A.
