What is the shape of the cross section of the figure that is perpendicular to the triangular bases and passes through a vertex of the triangular bases?

a parallelogram that is not a rectangle
a rectangle
a triangle that must have the same dimensions as the bases
a triangle that may not have the same dimensions as the bases

The shape of the cross section of the figure that is perpendicular to the triangular bases and passes through a vertex of the triangular bases is:

                     A rectangle.

From the figure attached to the answer we may clearly observe that the cross-section so obtained is a rectangle.

Also a triangle would have formed if the plane is perpendicular to the rectangular base and parallel to the triangular base.

Also, if a plane cuts a figure parallel to the given base so the cross-section so obtained is a figure parallel to it's base.

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

what is all that apply?
