How do you draw a line of symmetry for an equilateral triangle?
The first line is drawn from vertex A passing through the side BC, the second line is drawn from vertex B passing through the side A, the third line is drawn from vertex C passing through the side AB. Therefore, an equilateral triangle has 3 lines of symmetry. Hence, option (c) is the correct answer.
Do equilateral triangles have symmetry?
An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3.
What is the symmetry of an equilateral triangle?
3 lines of
Answer: An equilateral triangle has 3 lines of symmetry.
How many lines of symmetry does an equilateral triangle have?
3
Equilateral triangle/Line of symmetry
What has no line of symmetry?
A scalene triangle, parallelogram, and a trapezium are three examples of shapes with no line of symmetry.
Which figure has only 1 line of symmetry?
trapeziums
Trapezium. A trapezium has rotational symmetry of order one. Some trapeziums have one line of symmetry. They are called isosceles trapeziums as they have 2 sides of an equal length like isosceles triangles.
Do equilateral triangles have equal angles?
Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.
What shape has more than one line of symmetry?
circle
There are figures and shapes that can have more than one lines of symmetry. A circle has infinite lines of symmetry. Likewise, a triangle has three lines of symmetry, while rectangle and square have four such lines which divide them into identical parts.
How many symmetries of equilateral triangle?
The equilateral triangle has three lines of symmetry whereas a scalene triangle does not have any line of symmetry as its all sides are different. An isosceles triangle has one line of symmetry as both of its sides are equal.
Does equilateral triangle have two equal sides?
Any equilateral triangle (it has all 3 equal sides) is isosceles (that requires only 2 equal sides), but not all isosceles triangles (it has 2 equal sides) are equilateral (that requires all 3 equal sides). See all questions in Angles with Triangles and Polygons.
Does an isosceles triangle have any rotational symmetry?
A right-angled isosceles triangle has one line of symmetry. It has rotational symmetry of order 1. It has 2 sides of equal length. It has an angle of 90° and two angles of 45°.
