Question

Determine if the statement is mathematically valid. If the statement is valid, clearly explain why the statement is always true. If it's not, create a representation or write a clear explanation as to why the reasoning is incorrect.

a. All rectangles have 4 lines of symmetry (horizontally, vertically, and the two diagonals), along with 2 rotational symmetries (180° and 360°).

b. For all prisms, the number of vertices is equal to double the number of sides in the base. For all pyramids, the number of edges is equal to double the number of sides in the base.

Answer 1

also B is false in case of pyramid

No. Of vertices in pyramid = n+1

No. Of eges or sides =2n

Which double is 4n which is not equal to n+1
