## Why is the triangle the strongest shape used in construction?

The **triangle** is the **strongest** to as it holds it **shape** and has a base which is very strong a also has a strong support. The **triangle** is common in all sorts of building supports and trusses. The overall **shape** of many bridges is in the **shape** of a catenary curve. Freely hanging cables naturally form a catenary curve.

## Why are triangles useful?

**Triangles** are **used** in bridges because they evenly distribute weight without changing their proportions. When force is applied on a shape like a rectangle it would flatten out. Before **triangles** were **used** in bridges, they were weak and could not be very big. Architects use many **triangles** in bridges.

## Where triangles are used in real life?

**Triangles are used** in supporting the structure of the bridges because they evenly distribute the weight without changing the proportions. When force is **applied** on a rectangular shape, it will flatten out.

## Why are triangle structures so stable?

The simple answer is that **triangles** are **stable**. A **triangle** has three sides and, if these are fixed in length, there is only one configuration they can be in. Without changing any of the lengths of the sides the shape can be skewed/squashed or deformed. **Triangles** help keep **structures** rigid.

## What is the strongest shape in the universe?

**The triangle** is the strongest shape, capable of holding its shape, having a strong base, and providing immense support.

## What is the weakest geometric shape?

The **Triangle** is a solid shape. The weakest areas include hitting, locking, stances, moving and so on.

## What are the 2 types of special right triangles?

**The two special right triangles include:**

- 45°; 45°; 90°
**Triangle**. - 30°; 60°; 90°
**Triangle**.

## What makes similar triangles?

If two pairs of corresponding angles in a pair of **triangles** are congruent, then the **triangles** are **similar**. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

## How are congruent triangles used in real life?

By utilizing congruent triangles the buildings create a nice work atmosphere(office buildings), a protection system from the sun by reflecting off opposite triangular faces, or even a popular tourist attraction. This is an **example** of triangle congruence in the real world- identical buildings.

## What is a real triangle?

Properties of a **Triangle**

A **triangle** has three sides, three vertices, and three angles. The sum of the three interior angles of a **triangle** is always 180°. The sum of the length of two sides of a **triangle** is always greater than the length of the third side.

## How many kinds of triangles are there?

To learn about and construct the seven **types of triangles** that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.

## Are triangles or hexagons stronger?

The **hexagon** is not the **strongest** shape, the **triangle** is. If you have a **triangle**(3 straws you can not change its shape without breaking or bending a straw. If you have more sides, a little pressure will change the shape although the straws do not bend. The **hexagon** is made of **triangles**.

## What is the strongest point of a triangle?

An equilateral **triangle** is structurally the most sound for obvious reasons. Equal angles and vectors naturally resist gravitational and lateral forces equally in all directions.

## Are circles stronger than triangles?

The answer is the **triangle**, because of the way it distributes pressure. I’m assuming you’re referring to an equilateral **triangle**? The **circle** ie the **strongest** shape because it maintains constantly pressure, There is no inherent leverage as all points are at a constant distance from each other.
