What is a triangle with one mirror line?
a reflection
How many lines of symmetry in an isoceles triangle?
There is only one line of symmetry in an isosceles triangle. If you draw this triangle with the "odd" side as the base and then bisect it with a vertical line, you will have that one line of symmetry. The triangle can be folded in half along this line because each side is a mirror of the other.
What shape with just one line of symmetry?
Triangle, trapezoid
How many lines of symmetry does an isoceles triangle have?
It has just one line of symmetry
Can you show me a triangle with only one line of symmetry?
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
What type of triangle has 1 line of symmetry?
An equilateral triangle and an isoceles triangle have one line of symmetry.
A triangle with one line of symmetry?
An isosceles triangle
What figures has one line of symmetry?
Here are just some: Triangle, trapezoid, cone
What triangle has only one line of symmetry?
An isosceles triangle
How do you divide a triangle into 2 triangles and 2 trapezoids?
Let's assume the triangle has points A, B, and C. Method 1 (3 lines) Draw two lines across the triangle parallel to line segment AB. Now you have two trapezoids and one triangle. Draw another line from C to the any point on the closest of the two lines you just drew, splitting the triangle into two more triangles. Method 2 (2 lines) Draw one line across the triangle parallel to line segment AB. Now you have one trapezoid and one triangle. Draw a second line that passes through C and is perpendicular to AB, splitting the trapezoid into two trapezoids and the triangle into 2 triangles. Method 3 (3 lines) Draw one line from point C to any point on line segment AB. Then draw a line parallel to AC and one parallel to BC, but don't let them cross the line you just drew.
Why does a triangle with line symmetry have to be isosceles?
The basis of symmetry is that everything on one side of an imaginary line is the same as the other. This means that if you split a triangle down the middle by an imaginary line, one side of the triangle on both halves will be the same. This defines an isosceles triangle. An equilateral triangle also has line symmetry.
Is there a triangle that has exactly one line of symmetry?
Yes and it is an isosceles triangle.
