If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side
How do you find the perpendicular height of a triangle?
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.
When dilating a triangle to enlarge the triangle you must use a scale factor that is 1 1 equals 1 equals 0?
No, there cannot be a zero in any scale factor.

a scale factor of 4.5 is your answer
What jobs use scale factor in them?
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.
How do you enlarge a rectangle by 2.5 with scale factor?
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.
How do you find a separate set of lengths for a similar triangle?
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.
How can you use scale factor to find a new perimeter and area?
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
What opperation do you use whene a scale factor is given to you?

How do you scale-up a drawing?
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.
What is the use of gray scale ratio in adobe photoshop?
It is factor to scaling down the image.
What is Scale Factor?
The number used to multiply the lengths of a figure to stretch or shrink it to a similar image. If we use a scale factor of 3, all the corresponding lengths in the original side lengths will be multiplied by three.
What are two ways scale factor is used in real life?
If you are trying to read a map, there is MOST LIKELY a scale factor (i.e. 1 inch=2.5 miles. You could also use it in blueprints, like if you want to rearrange you bedroom. You can't fit your bedroom on a piece of computer paper! So you may use a scale factor for that (i.e. 1/2 in.= 1 foot).
