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.
No. Scalene:no sides equal. Isosceles: 2 sides equal.
A triangle with two equal sides and two equal angles is called an isosceles triangle.
An isoceles triangle has 2 sides of equal length
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.
By adding up all of the sides. To find the area, do base (bottem) X height X 1/2
Its not a triangle if it has only two sides.
If you know the 2 other angles, apart from the right angle you can calulate the other 2 sides.
Unless you are given atleast 2 other angles, there is no way to find them out.
The midpoint of a triangle is the 3rd sides' size, divided by 2.
By using sides we get area of triangle and then using (1/2)heightxbase we get height.
Two sides of an isosceles triangle are equal to each other.
You add the 2 other sides together, then minus that number off 180.
All sides are equal on an equilateral triangle. All the sides are different lengths on a scalene. 2 sides are larger then the other 1 on a isosceles triangle.
Measure it with a rule or find its perimeter and subtract the other 2 sides from it
An isosceles triangle has two congruent sides.
There cannot be a "medium triangle with 5 sides". A triangle can have 3 sides and only 3 sides. Any other number of sides and it is not a triangle.
An isosceles triangle has 3 sides 2 of which are equal in length
