Triangle with 2 lines of symmetry?
A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.
5 shapes that have 1 line of symmetry?
The five shapes that have one line of symmetry are equilateral triangle, isosceles triangle, scalene triangle, rectangle, and rhombus. A shape has one line of symmetry if it can be folded along a line so that the two halves match exactly. In the case of these shapes, there is only one line that can divide the shape into two congruent halves.
Using the numbers 1-9 in a triangle the sum along each side equals 17?

How many edges in a triangular based pyramid?
Six - a pyramidic form with a triangular base is going to have three edges along the periphery of the base. There will be three planar surfaces that comprise the "upright" side surfaces, each of which will also be triangular in shape and sharing common edges with those triangular surfaces on either side. Visualize it by drawing an equilateral triangle on a sheet of paper. Next, bisect each interior angle of that triangle, stopping each bisector where it intersects with the other bisectors. Now count the line segments that extend from apex to apex and add to that number the line segments that extend from an apex to the bisector intersection. Total count is six line segments... thus six edges.
Can a square and a triangle tessellate together?
No * * * * * Yes it can: and in many ways. One possible way is to add a right isosceles triangle to each side of the square (with the hypotenuse along the square) to make it a larger square!
If an equilateral triangle is reflected along one of its edges what shape is created?
Trapezoid
If an equilateral triangle is reflected along one of it's edges what shape is created?
trapazoid
If an equilateral triangle is refelcted along one of its edges what shape is created?
A rhombus
What do you get if you cut an equilateral triangle in half along a line through one vertex?
A 30-60-90 right triangle
If each side of the equilateral triangle measures 9c find the height of the triangle?
The area of a triangle is one-half the product of the triangle's base and height. The height of an equilateral triangle is the distance from one vertex along the perpendicular bisector line of the opposite side. This line divides the equilateral triangle into two right triangles, each with a hypotenuse of 9c and a base of (9/2)c. From the Pythagorean theorem, the height must be the square root of {(9c)2 - [(9/2)c]}, and this height is the same as that of the equilateral triangle.
Does a right-angled triangle have any equal sides?
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.
what- a child folds a rectangular strip of paper repeatedly along the dashed lines, as shown. The first triangle is labeled?
FHG is isosceles but not necessarily equilateral
How do you find the height of an equilateral triangle if you don't know its area and you only know that each side is equal to 41.3m?
Cut it exactly down the middle, along its height, and put one piece aside. The remaining side is a right triangle. The slanting side of the right triangle is a whole side of the original equilateral triangle, the bottom is half of an original side, and the vertical line is the height of the original triangle. Now you have a right triangle and you know the lengths of two of its sides, so you use what you know about right triangles to find the length of the third side, which is the height of the original equilateral triangle. It turns out to be 0.866 times the side of the equilateral triangle. (rounded) Technically, that's (1/2) x (side) x sqrt(3)
How do you draw duval triangle?
The Duval triangle is a diagnostic tool for oil insulated equipment. The three sides of an equilateral triangle form the axes representing the relative concentrations of methane (CH4), ethylene (C2H4) andacetylene (C2H2).The methane concentration is plotted along the axis with a positive gradient, ethylene along the axis with the negative gradient and acetylene along the horizontal axis : but going in the from right to left.The triangle is divided into a number of zones which indicate the most likely cause of failure.The Duval triangle is a diagnostic tool for oil insulated equipment.

You are a polyhedron all of your faces are the same all of you faces are equilateral triangles you have eight faces?
that's easy its a triangle * * * * * That is such a nonsensical answer! A triangle is not even a polyhedron. The correct answer is an octahedron - two square based pyramids stuck together along their bases.
What does the Puerto Rico flag look?
The flag of Puerto Rico is a rectangle with an equilateral triangle placed with one side along the left edge of the rectangle. The triangle is blue with a single white star in the middle. The part of the rectangle not "covered by the triangle has a red stripe along the top and bottom and in the middle. Between the red stripes are two white stripes. All stripes are of equal thickness.
Where is the line of symmetry for a triangle?
A line of symmetry for a triangle is a line along which a triangle can be folded so that either side of the line is a mirror image shape of the other.An Isosceles triangle, with two equal sides, has a line of symmetry from the center of the base to its opposing vertex.An equilateral triangle with three equal sides has three lines of symmetry, each from the center of a side to its opposing vertex.Any other triangle type, called a scalene triangle, has no lines of symmetry,
