💡 Hint

Common Mistakes

Entering a shape name instead of a number.

Using a number less than 3.

The POLYGON command requires the number of sides as the first input. For example, 3 creates a triangle.

2fill in blank

Complete the command to specify the polygon's center point at coordinates (10, 10).

POLYGON 6 C [1]

B10 10

C10,10

D[10,10]

💡 Hint

Common Mistakes

Using commas or brackets in coordinates.

Entering coordinates in parentheses.

AutoCAD expects coordinates as space-separated values without parentheses or brackets.

Fix the error in the command to specify the polygon's radius as 5 units.

💡 Hint

Common Mistakes

Typing extra words before the number.

Adding letters like 'L' before the number.

The 'I' option expects a numeric value for the radius directly, without extra words or letters.

4fill in blank

hard

Fill both blanks to complete the command that creates a polygon with 7 sides, centered at (0,0).

AutoCAD

POLYGON [1] C [2]

Drag options to blanks, or click blank then click option'

C0 0

D10 10

💡 Hint

Common Mistakes

Using wrong number of sides.

Entering coordinates with commas or brackets.

The first blank is the number of sides (7). The second blank is the center point coordinates (0 0).

5fill in blank

hard

Fill all three blanks to complete the command that draws a polygon with 9 sides, circumscribed about a circle, centered at (5,5).

AutoCAD

POLYGON [1] [2] [3]

💡 Hint

Common Mistakes

Mixing up 'C' and 'I' options.

Entering coordinates with commas.

The polygon has 9 sides (A), is centered (C), and the center point is at 5 5 (C). The 'C' option specifies center point input.

Practice

1.

What does the POLYGON command in AutoCAD primarily create?

easy

A. A freehand drawing

B. A regular shape with equal sides

C. A 3D solid object

D. A text annotation

Solution

1. Step 1: Understand the purpose of POLYGON command

   The POLYGON command is designed to create shapes with equal-length sides and equal angles.

2. Step 2: Identify the shape type created

   Since it creates regular polygons, the shape has equal sides and angles.

3. Final Answer:

   A regular shape with equal sides -> Option B

4. Quick Check:

   POLYGON = Regular shape with equal sides [OK]

Hint: POLYGON always draws shapes with equal sides [OK]

Common Mistakes:

• Thinking POLYGON creates freehand drawings
• Confusing POLYGON with 3D modeling commands
• Assuming POLYGON creates text or annotations

2.

Which of the following is the correct first step when using the POLYGON command in AutoCAD?

easy

A. Choose the polygon color

B. Draw a circle first

C. Enter the center point of the polygon

D. Specify the number of sides

Solution

1. Step 1: Recall the POLYGON command sequence

   The first prompt after starting POLYGON is to specify the number of sides.

2. Step 2: Confirm the initial input required

   You must enter how many sides the polygon will have before placing it.

3. Final Answer:

   Specify the number of sides -> Option D

4. Quick Check:

   First step = Number of sides [OK]

Hint: Always start POLYGON by entering sides count [OK]

Common Mistakes:

• Trying to pick center point before sides
• Drawing a circle before POLYGON command
• Selecting color before shape creation

3.

What will happen if you enter 6 for sides, specify the center point, and choose inscribed circle option with radius 10 in the POLYGON command?

medium

A. A hexagon fits inside a circle of radius 10

B. A hexagon circumscribes a circle of radius 10

C. A circle with radius 10 is drawn inside a hexagon

D. A hexagon with sides length 10 is drawn

Solution

1. Step 1: Understand inscribed polygon meaning

   An inscribed polygon fits inside the circle, touching it at vertices.

2. Step 2: Apply to a hexagon with radius 10

   The hexagon's vertices lie on the circle of radius 10, so it fits inside that circle.

3. Final Answer:

   A hexagon fits inside a circle of radius 10 -> Option A

4. Quick Check:

   Inscribed polygon = inside circle [OK]

Hint: Inscribed means polygon inside circle touching vertices [OK]

Common Mistakes:

• Confusing inscribed with circumscribed
• Assuming side length equals radius
• Thinking circle is inside polygon

4.

You used the POLYGON command and entered 5 sides, then clicked a center point, but the polygon does not appear. What is the most likely error?

medium

A. You did not specify inscribed or circumscribed option

B. You entered an invalid number of sides

C. You did not specify the radius or edge length

D. You forgot to press Enter after center point

Solution

1. Step 1: Recall POLYGON command steps

   After center point, you must specify radius or edge length to define polygon size.

2. Step 2: Identify missing input

   If polygon does not appear, likely radius or edge length was not entered.

3. Final Answer:

   You did not specify the radius or edge length -> Option C

4. Quick Check:

   Missing radius/edge length = no polygon drawn [OK]

Hint: Always enter radius or edge length after center point [OK]

Common Mistakes:

• Skipping radius input thinking center point is enough
• Confusing inscribed/circumscribed as mandatory first step
• Assuming polygon draws automatically after center point

5.

You want to draw a regular octagon that exactly fits around a circle with radius 15. Which option should you choose after specifying the center point in the POLYGON command?

hard

A. Circumscribed about circle

B. Inscribed in circle

C. Draw polygon freehand

D. Specify side length as 15

Solution

1. Step 1: Understand circumscribed polygon meaning

   A circumscribed polygon surrounds the circle, touching it at the midpoint of each side.

2. Step 2: Match polygon to circle radius

   To fit the polygon around the circle of radius 15, choose circumscribed option so polygon edges touch the circle.

3. Final Answer:

   Circumscribed about circle -> Option A

4. Quick Check:

   Polygon around circle = Circumscribed [OK]

Hint: Choose circumscribed to fit polygon around circle [OK]

Common Mistakes:

• Choosing inscribed which fits polygon inside circle
• Trying to draw freehand polygon
• Using side length instead of circle radius
