Answer 3

Consider asking this in the Mathematics subject group next time.

Scale drawings are 2D drawings that represent a real place or thing but on a reduced scale. Think of floor plans or blueprints of houses.

Cross-sections of a rectangular pyramid look a lot like conic sections, if you know what those are, they're just slices inside of the 3D shape that can make a horizontal or vertical 2D shape on the inside.

Verticle angles are created from a pair of intersecting lines with opposite angles. They should have 2 obtuse angles on the top and bottom and 2 acute angles on the left and right.

Supplementary angles have a sum of 180 degrees. Complementary angles have a sum of 90 degrees. Neither have to be adjacent or share a vertex.

The circumference is found by applying the formula\[2\pi r\] and to find the area, you use
\[\pi r^2\]
The length of a circle's outline is its circumference. The area is all the space inside the circle.
