## How many squares and rectangles can be drawn by a set of four straight parallel lines?

14 squares and 9 rectangles can be formed.

## How many parallelograms can be formed from a set of 4 parallel straight lines intersecting a set of 3 parallel straight lines?

18 numbers

From the above solution, we have found that 18 numbers of parallelograms can be formed from a set of four parallel lines intersecting three parallel lines. Hence, the correct option is (b).

**What shape has 4 pairs of perpendicular lines?**

The only regular shape to have perpendicular lines is a square. A square has 4 corners that have right angles, therefore at each corner you have a pair of perpendicular lines.

**How many parallelograms are formed by a set of 4 parallel lines intersecting another set of 5?**

Thus 60 parallelograms are formed.

### What is drawing set square?

A set square or triangle (American English) is an object used in engineering and technical drawing, with the aim of providing a straightedge at a right angle or other particular planar angle to a baseline.

### How many set squares are used in basic technical drawing?

There are two main types of set square. One has an angle of 45 degrees and the other 30/60 degree angles. The 45 degree set square also has a 90 degree angle. This can be used for drawing vertical lines.

**How many parallelograms can be formed from 4 vertical and 4 horizontal slanting lines?**

∴ The required result will be 36.

**How many parallelograms are there?**

The simplest parallelograms are ABFE, BCGF, CDHG, EFJI, FGKJ and GHKL. These are 6 in number. The parallelograms composed of two components each, are ACGE, BDHF, EGKI, FHLJ, ABJI and CDLK. Thus, there are 7 such parallelograms.

#### What shape has 4 pairs of parallel lines?

A regular octagon is a shape that has 4 pairs of parallel sides. Each side is parallel to the side that is opposite to it.

#### How many parallel lines does a square have?

two pairs

Lesson Summary A square also has two pairs of parallel lines. A parallelogram also has two pairs of parallel lines.

**How many parallelograms can be formed by a set of 5 parallel?**

A set of 4 parallel lines intersect with another set of 5 parallel lines. How many parallelograms are formed?…Subscribe to GO Classes for GATE CSE 2022.
