A cross section of a solid is figure formed by the intersection of aand a solid when a planethrough rhe soild.​

first blank: three dimensional

Step-by-step explanation:

A cross section is the intersection of a three-dimensional figure and a plane.

A cross section is the shape we get when cutting straight through an object.

Different cross sections can be taken of the same solid. A plane can slice through a solid in any direction. The resulting figure of a cross section depends on how the solid is "sliced".

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
