How many vertices does a squared based pyramid have?

Answer 1

According to Euler's theorem= Edges+2=Vertices+Faces

No of faces= 5

No of vertices= ?

No of edges=8

8+2=5+vertices

10= 5+vertices

10-5 = vertices

5 vertices

Hence 5 vertices are present in square based pyramid.

This theorem works everywhere

Answer 2

5, the vertices are

a - (triangle1,triangle2,triangle3),

b - (triangle1, triangle2,square1),

c - (triangle2,triangle3,square1),

d - (triangle3,triangle4,square1),

e - (triangle4,triangle1,square1)

Answer 3

five vertices

Answer 4

5 vertices
