## What is the effect of variations in line weight?

This is how light or dark the line appears on the surface. By varying the lineweight within your drawings, you can add dimension and importance to certain elements. Various materials and the pressure you put behind it will affect the the strength of your lines.

### What are weighted lines?

Line weight is the visual lightness, darkness, or heaviness of a line within a drawing. In any architectural drawing, from a sketch to a construction drawing, the interplay of different relative line weights is used to communicate depth, importance, and proximity.

**What is line variation?**

Line Variation – adding interest to your lines is important in creating successful artwork. Length – lines can be long or short. Width – lines can be wide or skinny. Texture – lines can be rough or smooth. Direction – lines can move in any direction.

**What are the line weights used in drawing?**

if you only want to use two line weights, take the narrow and wide pair from each row. The default line weight in both Autocad and Inventor is 0.25mm. The recommended Line weight for the ‘Drawing frame’ (Border) for engineering drawings is 0.7mm.

## How many straight lines are there?

The slanting lines are LC, CF, FI, LI, EK and AG i.e. 6 in number. Thus, there are 5 + 3 + 6 = 14 straight lines in the figure….Exercise :: Analytical Reasoning – Section 1.

A. | 10 straight lines and 34 triangles |
---|---|

D. | 10 straight lines and 36 triangles |

### How many straight lines do you have with slope 1?

Theorem 8.3. A straight line may be specified by giving its slope and the coördinates of one point on it. Equivalently: Through any point there is exactly one straight line with a given slope.

**How many straight lines can be drawn through two given lines?**

1 straight line

**How many triangles and straight lines are there?**

9 straight lines and 36 triangles.

## Which one will replace the question mark?

Which number will replace the question mark ? Hence the number 26 will replace the question mark. Example 2.

### How many straight lines can be drawn from a point?

(i) Infinite line can be drawn through a given point. (ii) Only one line can be drawn through two given point.

**What is the minimum number of straight lines needed to obtain 8 triangles in the square?**

2 Lines

**Can you join all nine dots with four straight lines?**

One classical example is where nine dots are arranged on the sides and the center of a square as in the picture below. The problem is to connect the dots with no more than 4 straight lines without lifting your hand from the paper. First attempts are always frustrating. For one always comes up with 5 lines instead of 4.

## What is the minimum number of lines required to make a closed figure?

### How many squares are in a 5×5 grid?

25 squares

**How many squares are in a 3×3 grid?**

14 squares

**How many squares do you see 4×4?**

After they have had a chance to think about and have yelled out some more answers ask them how many squares there are in a 1×1 grid (1) and in a 2×2 grid (the 4 small squares and the 1 big square = 5) and a 3×3 grid (9 small squares, 4 of the 2×2, and 1 big one = 14). So the total for a 4×4 is 16 + 9 + 4 + 1 = 30.

## How many squares can you find in this shape?

The correct answer to the puzzle is 40 squares.

### How many squares are in this 2×2 grid?

5 squares

**How many squares are in a 10×10 grid?**

385 squares

**How many squares are there in a 7 by 7 grid?**

four squares

## How many squares are in a 6 by 6 grid?

Total squares: 24 + 15 + 8 + 3 = 50 squares. Answer: 50.

### How many squares are in a grid?

a 2×2 grid has 4 1×1 squares and a single 2×2 square = 5. a 2×3 grid has 6 1×1 (2 * 3) squares and 2 2×2 (2 * 1) squares = 8. (we solved this above.) If you continue this you can easily see that a 2 x m grid has 2*m + 1*(m — 1) squares in it.

**How many squares and rectangles are in a 3×3 grid?**

A 3×3 square board has 14 squares, the smaller 9 plus 4 2×2’s plus 1 3×3 one. A 4×4 square board has 30 squares, the smaller 16 plus 9 3×3’s, plus 4 2×2’s plus 1 4×4 one.

**How many squares are in a 8×8 grid?**

204

## How many rectangles are in a 3×5 grid?

If the grid is 1×1, there is 1 rectangle. If it grid is 3×1, there will be 3 + 2 + 1 = 6 rectangles. If we add one more column to N×1, firstly we will have as many rectangles in the 2nd column as the first, and then we have that same number of 2×M rectangles.
