## How can we make a triangle using 6 matchsticks?

This is an acute angle triangle and it is possible to make a triangle with the help of 6 matchsticks because sum of two sides is greater than third side.

## How many triangles can you make with 6 sticks?

So, imagine that you have a triangle with sides of three, four and five. The longest side, five, is less than the sum of the two other sides (3+4=7)….Age 7 to 11. Challenge Level.

Number of sticks | Number of triangles |
---|---|

6 | 1 |

7 | 2 |

8 | 1 |

9 | 3 |

**Can you form 6 congruent squares by moving 3 sticks?**

Answer 3: Yes there will be a serious problem. It will create a common stick 6 with the existing central square made up of sticks 5, 6, 7, 8. And move it straightaway to complete one of three remaining nearly complete squares, say square with three sides 11, 7, 9.

### How many matchsticks are needed to form a triangle?

20 matchsticks

Make all of the possible triangles that can be made from 20 matchsticks. You must use all 20 matchsticks for each triangle. You must record which triangles you have made in some way.

### What are the types of triangles based on angles?

Based on the angle measurement, there are three types of triangles:

- Acute Angled Triangle.
- Right-Angled Triangle.
- Obtuse Angled Triangle.

**How many triangles can you make with 20 matchsticks?**

eight

The fact that there are only eight possible triangles using 20 match- sticks intrigued Helen in the process of preparing this article.

#### Which angle is the smallest in this triangle?

opposite

The angle opposite the smallest side of a triangle has the smallest measure. Likewise, the angle opposite the largest side has the largest measure.

#### How many triangles can be made with 87 sticks?

Therefore, 43 triangles are formed with 87 sticks.

**How to draw a triangle with three sides?**

Triangle given three sides (SSS) This page shows how to construct a triangle given the length of all three sides, with compass and straightedge or ruler. It works by first copying one of the line segments to form one side of the triangle. Then it finds the third vertex from where two arcs intersect at the given distance from each end of it.

## What’s the best way to make a triangle?

Place the centre of the protractor on the end of the line and mark 40° with a dot. STEP 2: Use a ruler to draw a line from the end of the line through the dot and label the angle 40°. TIP: you won’t know the exact length of this new side yet so draw it a bit longer than you think you’ll need. You can always extend it later.

## How do you find the third angle in a triangle?

You’ve constructed a triangle, given the length of 1 side and 2 angles. TIP: if one of of the 2 angles is NOT at the end of the side you’re given, it’s easy to work out the third angle using the fact that there are 180° in a triangle.

**How do you divide a square into eight equal parts?**

Because all the sides of a square are equal, you know how to divide all sides equally. Once you have four rectangles, you can simply draw one horizontal line through the center of the square, dividing it into eight equal rectangles.
