## What do you call a triangle with one curved side?

Circular triangles are triangles with circular-arc edges, including the Reuleaux triangle as well as other shapes.

The deltoid curve is another type of curvilinear triangle, but one in which the curves replacing each side of an equilateral triangle are concave rather than convex..

## What are the 7 types of triangles?

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 all 3 sided shapes triangles?

A three-sided polygon is a triangle. There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Isosceles – has two equal sides, with the third one a different length.

## What is a triangle with two sides the same?

An isosceles triangle therefore has both two equal sides and two equal angles. … The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.

## How do you find the isosceles triangle with two equal sides?

A altitude between the two equal legs of an isosceles triangle creates right angles, is a angle and opposite side bisector, so divide the non-same side in half, then apply the Pythagorean Theorem b = √(equal sides ^2 – 1/2 non-equal side ^2).

## Does a triangle have two sides?

Triangles can be classified according to the lengths of their sides: An equilateral triangle has all sides the same length. An equilateral triangle is also a regular polygon with all angles measuring 60°. An isosceles triangle has two sides of equal length.

## Does a triangle need to have straight sides?

Must a triangle always have straight sides? … After all the criteria for a triangle is 3 straight line segments, 3 vertices, the sum of the angles of each vertex is 180 degrees and that the shape lies on a flat plane, i.e. it is two-dimensional. The moment you add in curves, the angles change too.

## How do you classify a triangle by its sides?

We can also classify triangles by their sides.scalene triangle-a triangle with no congruent sides.isosceles triangle-a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)equilateral triangle-a triangle with exactly 3 congruent sides.NOTE:

## How do you find the missing side of a triangle?

How to find the sides of a right triangleif leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)if leg b is unknown, then. b = √(c² – a²)for hypotenuse c missing, the formula is. c = √(a² + b²)

## What is the name of a triangle with 3 equal sides?

equilateral triangleAn equilateral triangle has three equal sides and angles.

## Is a sphere stronger than a triangle?

use cylinder or sphere shapes — or both. 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.

## Can a triangle have a curved side?

That technically is not a triangle. A “side” should be defined as a straight line, or a segment that falls between 2 corners. Any curved side of a shape represents an infinite number of sides, so it would not be a triangle, but in fact an infinity-gon.
