it sais for each solid below draw the cross section formed when the plane indicated by the lines intersects the figure.... theres cubes cylinders cones triangular pyramids and prisms and rect pyramids!! HELP!!!!!!!!

The cross section is the surface exposed when you make a straight cut trhough the 3d figure (or shape in this case) with the plane (indicated by your lines).
hope i was helpful

Dude, get a grip. It's the 2-D plane. Like 3-D is an orange, then the cross section is a circle. Just imagine it....so take the plane and pretend it's a knife cutting into an orange (the figure). What shape would it give? Assume the orange is the figure. Use your imagination. If all else fails just call it a "conic section". This will give you partial credit in the eyes of most professors.

To help you with this, imagine that the 3D shapes are made out of clay. If you were to cut them into two with a knife, you'll see the cross-section by looking at the cut faces. Get it? But you have to have good spatial intelligence to figure ahead of time what it would look like to cut different kinds of 3D shapes. A cylinder cut at an angle, for example, will give you a cross section that looks like an ellipse, for example.

Imagine you are cutting those figures in half at the lines intersecting as shown. You have to graphically represent what you'd see looking at the cut-section from the side.
For example, if you cut your forearm in half, the cross-section you'd draw would be the two circular shapes for the bones (ulna and radius) and all the flesh and skin around them.

Imagine cutting the solid into 2 pieces using the plan indicated - The two new (identical) faces (where you just cut) are the cross section

it incredibly is a honest question, even though it incredibly belongs in arithmetic or Physics. although right here's an answer for you. the assumption of a airplane circle has purely 2 dimensions. yet....on condition that we exist in time-area (3 or 4 dimensions looking on your POV) as quickly as we create a actual photograph of a airplane circle...then the image has 3 dimensions. to illustrate on incredibly paper a twin of the circle incorporates the ink molecules arranged contained in this style of a circle on the actual piece of paper which has a distinctive thickness. On a workstation video show the image incorporates pixels which even have 3 dimensions. incredibly we could no longer see something that has purely 2 dimensions. yet in our minds (imaginations) we can conceive of it.

It just means a slice of a shape. Three dimensional is like a cube (length, width, height), two dimensional is like a flat piece of paper (lengh and width). One dimensional is just a point, four dimensional is three dimensions plus time.

take the earth (a sphere) for example, if you cut it in half at the equator for example, and take one of the halves, you could see the layers of rock under the crust.. that is your cross section.
