By using Pythagoras' theorem for a right angle triangle.
The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
90 degree
The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
Use the formula 1/2 the base * the height
right triangle
A=bxh
The answer depends on what he formula is for and what other information is given.
By using Pythagoras' theorem for a right angle triangle.
The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!

The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
Use the formula 1/2 the base * the height
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
to find the area of any triangle follow the formula: 1/2(b*h) "B" - stands for the base of the triangle "H" - stands for the height of the triangle
Area=1/2(base*height) where either side can be the base or the height in a right triangle.
