Use the Pythagorean Theorem to determine the missing side. That is, if the sides are A, B, and C, C being the longest, then A2 + B2= C2. So if the long side is missing, side A is 3, and side B is 4, then 3 squared is 9 and 4 squared is 16. 9+16=25. The square root of 25 is 5, the length of the missing side of THAT triangle. Add all three sides together to get the perimeter.

If it is and equilateral triangle, the perimeter is 12, otherwise it is impossible to figure out without any angle measurements or other sides lengths
Using Pythagoras' theorem and the quadratic equation formula the sides of the triangle work out as 6.25 cm and 15 cm. Therefore the perimeter of the right angle triangle is: 6.25+15+16.25 = 37.5 cm
you multiply one of the sides by three. The perimeter is the total length of the outside of the shape - in this case the total of the lengths of the three sides. You'll need to know the length of one side and an angle to calculate the lengths of the others in any triangle, however in an equilateral triangle all the sides are the same length so if you know one you know them all.
== == The corresponding angle is 60 degrees.

The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
add all of the sides together

It works out as: 180 minus the 2 known angles = unknown angle

If it is and equilateral triangle, the perimeter is 12, otherwise it is impossible to figure out without any angle measurements or other sides lengths
Using the trigonometry sine rule the other sides of the triangle are 16.35cm and 13.62cm so it follows that its perimeter is 14.5+16.35+13.62 = 44.47cm
A right angle triangle fits the dimensions given
Using Pythagoras' theorem and the quadratic equation formula the sides of the triangle work out as 6.25 cm and 15 cm. Therefore the perimeter of the right angle triangle is: 6.25+15+16.25 = 37.5 cm
You can't calculate any angle if all you know is one side of the triangle.
