GEOMETRYHELP

Make an isometric drawing of the cube structure below.

You will draw all the edges of the figure that you can see.Start by drawing the front face of the figure. Next, draw the back edges of the figure. Finally, fill in the right face, top faces, and left edges.

Step 1:Draw the front.

Step 2:Draw the back.

Step 3:Complete.

Make an orthographic drawing of the isometric drawing below.

Orthographic drawings flatten the depth of a figure. An orthographic

drawing shows three views. Because no edge of the isometric drawing is

hidden in the top, front, and right views, all lines are solid.

(continued)

Because the top view is formed from 3 squares, show 3 squares in

the foundation drawing.

Identify the square that represents the tallest part. Write the number 2 in

the back square to indicate that the back section is 2 cubes high.

Write the number 1 in each of the two front squares to indicate that

each front section is 1 cube high.

Is the pattern a net for a cube? If so, name two letters that will

be on opposite faces.

The pattern is a net because you can fold it to form a cube. Fold squares A and C up to form the back and front of the cube. Fold D up to form a side. Fold E over to form the top. Fold F down to form another side.

After the net is folded to form a cube, the following pairs of letters are on opposite faces:

A and C are the back and front faces.B and E are the bottom and top faces.

D and F are the right and left side faces.

Draw a net for the figure with a square base and four

isosceles triangle faces. Label the net with its dimensions.

Think of the sides of the square base as

hinges, and “unfold” the figure at these

edges to form a net. The base of each of

the four isosceles triangle faces is a side

of the square.
