The number of vertices in a pyramid is equal to the number of faces. How many vertices does a regular pyramid with 40 edges have?

Answer: 10 verticesTo make a full circle (360 °), the number of 40° lines you need will be: 360/40=9 lines. So, the base of the pyramid would be made of 9 lines. Pyramid has a base and sides. The sides number is equal to the number of lines of the base. Then, the number of faces/vertices would be: 1 + 9 = 10

If the question saying literally 40 edges (not degrees), then the pyramid base would be 40 lines. In this case, the number of vertices would be: 1+40=41
