## How many lines are there in isosceles triangle?

A triangle is only said to be an isosceles triangle if it has 2 equal sides. Therefore every isosceles triangle by definition has **1 line of symmetry**. It can be drawn by joining the vertex between equal sides and the midpoint of the opposite side.

## Can an isosceles triangle have 3 lines of symmetry?

**isosceles triangle has at least one line of symmetry**and an equilateral triangle has three lines of symmetry.

## How many lines of symmetry does a triangle have?

## Does a triangle have 4 lines of symmetry?

An equilateral triangle which has three equal sides has three lines of symmetry. This is because you can fold an equilateral triangle in half three…

## Which triangle has two lines of symmetry?

## What is the rotational symmetry of an isosceles triangle?

Order 1

## Does an isosceles right triangle have reflection symmetry?

CongruentCongruent figures are identical in size shape and measure. Isosceles TriangleAn isosceles triangle is a triangle in which exactly two sides are the same length. … **reflection symmetryA figure has reflection symmetry if it can be reflected across a line and look exactly the same as it did before the reflection**.

## How many lines are in a triangle?

Loh: “A triangle is made of three lines.Aug 26 2019

## Can a triangle have 2 lines of symmetry?

**An isosceles triangle has**one line of symmetry as both of its sides are equal. … These shapes are said to have Two Lines of Symmetry.

## What is the symmetry of a triangle?

Equilateral Triangle (all sides equal all angles equal) | Isosceles Triangle (two sides equal two angles equal) | Scalene Triangle (no sides equal no angles equal) |

3 Lines of Symmetry |

## Which lines are lines of symmetry?

## Which figure has exactly four lines of symmetry?

**Square**.

**A square**has four lines of symmetry.

## Which shape has no lines of symmetry?

Two shapes that have no lines of symmetry are the **scalene triangle** and an irregular quadrilateral.

## Why isosceles triangle does not have rotational symmetry?

An isosceles triangle is a triangle with at least two equal sides. … In the case of an equilateral triangle the shape remains the same each time the triangle is rotated by 120 degrees. As a subset of isosceles triangles equilateral triangles have rotational symmetry.

## Why isosceles triangle has no rotational symmetry?

**order 1**.

## How many lines of symmetry are there in a square?

4

## Does isosceles triangle have lines of symmetry?

1

## How many equal sides does an isosceles triangle have?

**two equal sides**and two equal angles or with two acute angles and one obtuse angle.

## What is symmetry line?

**a line that cuts a shape exactly in half**. This means that if you were to fold the shape along the line both halves would match exactly. Equally if you were to place a mirror along the line the shape would remain unchanged. A square has 4 lines of symmetry as shown below.

## Can you draw a triangle which has exactly one line of symmetry?

(a) Yes. **An isosceles triangle** can be drawn that has only 1 line of symmetry.

## What are the 4 types of symmetry?

Types of symmetries are **rotational symmetry reflection symmetry translation symmetry and glide reflection symmetry**. These four types of symmetries are examples of different types of symmetry on a flat surface called planar symmetry.

## How many lines of symmetry does an isosceles trapezoid have?

1

## Do 3D shapes have lines of symmetry?

Recall that the 3D symmetry line segments of a **symmetric 3D shape are all parallel to one another** and the same is true in any 2D orthographic projection of the 3D shape. This is the only invariant of 3D mirror symmetry. Consider an asymmetric 3D polyhedron with parallel line segments (Figure 4d).

## What are the symmetries of a square?

The square has **four lines of symmetry** indicated in gray in figure 1. There are the two axis and the two lines y = x and y = x. If we turn the square 180 about one of these lines we get a symmetry.

## Does the letter Z have a line of symmetry?

That’s right! **The Z is has no lines of symmetry**. The W and Y have one line of symmetry.

## What triangle has 3 lines of symmetry?

**An equilateral triangle**has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides.

## What other name can you give to the line of symmetry of an isosceles triangle?

**median and the altitude of the triangle**. From the above diagram it can be observed that the line of symmetry of the circle is infinite. Thus in a circle the other name of the line of symmetry is the diameter of the circle.

## Does 180 Degree have rotational symmetry?

An object has rotational symmetry if that figure is **itself after** you rotate it less than 180 degrees. If it is itself after exactly 180 degrees no more no less then that figure has point symmetry.

## Do all triangles have rotational symmetry?

With respect to rotation symmetry **only the equilateral triangle has rotation symmetry**.

## How do you find the rotational symmetry of a triangle?

For example for an equilateral triangle ABC when it is rotated about point X will take the same shape after a rotation of angle 120° as in figure. Thus order of rotational **symmetry = 360°/120° = 3**.

## How many lines of bilateral symmetry does a square have?

**4 lines**of symmetry.

## How many lines of bilateral symmetry are there in a square?

**four lines**of symmetry.

## How many lines of symmetry does a an isosceles triangle B a square have *?

**one 1 line**of symmetry which is PU.

## What are the rules for an isosceles triangle?

The rule for an isosceles triangle is that **the triangle must have two sides of equal length**. These two sides are called the legs of the triangle and the unequal side is called the base. The isosceles triangle theorem further states that the angles opposite to each of the equal sides must also be equal.
