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.
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.
One-half the base.
You have to use trig. If the base angle is a and base b, the height is b tan(a).
It is impossible to find the height of a triangle with just it's base.
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.
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.

One-half the base.
Area = 0.5*base*height You will need to know the base or height then use Pythagoras theorem to find the base or height.

The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
Area = 0.5*Base*Height

To locate the height of a non-right triangle, you may need to extend the base of a triangle. Then pick one corner and draw a line perpendicular to the extended base. This line you just drew is the height. Finding this height will depend on what triangle dimensions you are given, so the answer will vary. Note: the extended part does not count as the actual base. It is only used to help you find the height of a triangle.
