You measure them. If you want to calculate them, you need some information on which to base your measurements. For example, if you only know the length of one side, you don't have enough information. In general you need three items of information about a triangle, to be able to calculate the remaining triangle - and sometimes, even that isn't enough.

A scalene triangle is an isoceles triangle?
No. Scalene:no sides equal. Isosceles: 2 sides equal.
A Triangle that has 2 sides of equal length?
A triangle with two equal sides and two equal angles is called an isosceles triangle.
What is a isoceles triangle?
An isoceles triangle has 2 sides of equal length
What type of triangle has sides 3cm 4cm and 5cm?
The triangle with sides measuring 3cm, 4cm, and 5cm is a right triangle. This can be determined by applying the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, 3^2 + 4^2 = 5^2, confirming that the triangle is a right triangle.
How do you find the perimater of a triangle?
By adding up all of the sides. To find the area, do base (bottem) X height X 1/2
