does a triangle really have infinity lines of symeteray or just a very big number of them?

Question

CUS I REALLY WANT TO KNOW

Answer 1

no, a circle has infinite lines of symetry. For an equilateral triangle, i believe there r only 3

Answer 2

An equilateral triangle will have 3 lines of symmetry, extending from the vertex to the mid-point of the line opposite it.

An isosceles triangle will have 1 line of symmetry, extending from the vertex, that has a different angle to the other 2 vertices, to the mid-point of the line opposite (where its end meet the 2 angles of the same size).

A scalene triangle does NOT have any lines of symmetry.

It is the circle that has infinitely many lines of symmetry.

Answer 3

I've got to agree with all the others. A triangle will only have 3, 1 or 0 lines of symmetry depending on its properties.

Answer 4

no a circle does though as long as the symmetrical line runs straight and through the radius of a circle. a triangle can have some or none

an equilateral triangle can have 3 (one from each corner since the angles and sides are equal)
an isosceles triangle has one (two sides are equal and it runs between where the two equal sides meet to form the angle.
scalene has non because nothing is congruent check ya later ♥

Answer 5

A triangle does not have infinite lines of symmetry, it can have one or three, depending on how many of its sides are the same length.
An equilateral triangle (all three sides the same lenght) has 3 lines of symmetry, each passing througn one corner and through the middle of the opposite side.
An isoceles triangle (two sides the same length) has one line of symmetry, passing through the corner between the two sides the same length and the middle of the opposite side.
A scalene triangle (no sides the same length) has no lines of symmetry.

Answer 6

Triangle has a limited number of lines of symmetry.

A perfect circle has infinite lines of symmetry to the point of division [how close you allow each line to be] technically it would be possible to define the number of lines but let it be!

Answer 7

Well I can think of several lines that aren't symmetrical on a triangle, so it can't have an infinite amount of lines of symmetry. In fact I'd have thought if its an equilateral triangle, it must have 3 lines, if its an isoceles it has one, and if its scalene it has none....

Answer 8

I think that there is only 3 lines of symmatry in a triangle. You can try one ot yourself.

Answer 9

how can a triangle be made of infinte lines.. obviously its made of just 3 lines... n yeah i agree a circle has infinite lines of symmetry

Answer 10

yes.because a point is point in larger units of measurement but for smaller units it is a line or may be a circle or an ellipse just check it out with a microscope.
