square both the base and the height and add that together, and then take the square root of that answers and that's the last side
This is called the Pythagorean Theorem: a2+b2=c2 where a and b are the legs (base and height) and c is the hypotenuse (or longest side)

That is true, but only if the triangle is a right angled triangle. In other cases, the answer is indeterminate.

How do you find the area and perimiter of a triangle?
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
To find the area of a right triangle multiply height by what?
One-half the base.
What is the height of a triangle when its the base is 10cm?
It is impossible to find the height of a triangle with just it's base.
How do you find the height of a right triangle with only knowing its base and base angle?
You have to use trig. If the base angle is a and base b, the height is b tan(a).
How to find the attitude of a triangle?
If you mean "altitude", and by that you mean the height of the top of the triangle above its base, then draw a line from the top of the triangle to the base, at right angles to the base, and measure that line. Alternately, the height of a triangle above its base is twice the area divided by the base length.
How can you find the base of a right triangle when you have the height and hypotenuse?
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.

What is the area of a right triangle and the hypotenuse is 10.6?
Area = 0.5*base*height You will need to know the base or height then use Pythagoras theorem to find the base or height.

How do you find the square meters of a right triangle?
The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
How do you find the area of the right angle triangle given the base hypotenuse and perimeter?
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
How do you find the area of a triangle if you have base and height?
Area = 0.5*Base*Height
Find the area of a right triangle with a base of 8cm and a height of 12cm?
=48
How do you get the height of a triangle?
To find the height of a triangle you measure it. It has to be from the middle of the base to the top point.
