The way you use a scale factor to enlarge a triangle is to multiply each side of the triangle by that scale factor. Your triangle will then be that many times larger.

If you are given a picture of a triangle and no information about it, then you could use a protractor.
If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side
If it is a right triangle, you can use the Pythagorean theorem to find the height since it will be on of the sides. If it is an equilateral triangle, you can break it up into two right triangles and use the part above. If it is an oblique triangle, you use the angles and some trigonometry to find it. Since the area is 1/2 b x h, if you are given the area, you can solve for the height.
Do you mean an equilateral triangle? Then if so then the formula for the area of any triangle: 0.5*a*b*sinC whereas a and b are the embraced sides of angle C And in the case of an equilateral triangle it is: 0.5*any side squared*sin(60 degrees) Alternatively use Pythagoras' theorem to find the altitude of the triangle then use: 0.5*base*height = area
No, there cannot be a zero in any scale factor.
a scale factor of 4.5 is your answer
To enlarge a figure on a coordinate graph, you can apply a dilation transformation using a scale factor. Choose a center point for the dilation, often the origin or the center of the figure, and multiply the coordinates of each vertex by the scale factor. For example, if you use a scale factor of 2, each coordinate (x, y) becomes (2x, 2y), effectively doubling the size of the figure while maintaining its shape and proportions.
If you assume that 2.5 refers to the scale factor, you multiply each linear measurement by 2.5. This includes the width, the length, and - if you want to use it to construct your new rectangle - the diagonals. It also happens to include the perimeter, but you probably won't need that to construct the rectangle.
just use a scale factor! multiply all the dimensions by X and you'll have the dimensions of the new triangle. of course the angles and all are the same b.c theyre similar.
The scale gives the ratio that compares the measurements of the drawing or model to the measurements of the real object. Scale factor is a scale written as a ratio without units in simplest from.
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
multiplication
Surveying and land use jobs which use a map to scale. Also construction jobs will use plans of the building which are drawn to scale with a stated scale factor.
designing a scale model
If you increase a shape by a scale factor of 2, you double the height and double the width. If you increase a shape by a scale factor of 3, you treble the height and treble the width. If you are interested in doing this mechanically, use a pantograph.
It is factor to scaling down the image.
