# How do you find the height using the Pythagorean Theorem?

### How do you find the height using the Pythagorean Theorem?

We can find the height by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them. h = 13.

### Can you use the Pythagorean Theorem for all triangles?

Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

### How do you find X in Pythagoras?

### How do you find the height of a triangle if all sides are known?

How to find the height of a triangle - formulas

1. area = b * h / 2 , where b is a base, h - height.
2. so h = 2 * area / b.

### How do you use the Pythagorean Theorem to find the length of an isosceles triangle?

### How do you use the Pythagorean Theorem to find right triangles?

Right Triangles and the Pythagorean Theorem

1. The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
2. The side opposite the right angle is called the hypotenuse (side c in the figure).

### Does Pythagorean Theorem apply to non right triangles?

So the Pythagorean Theorem works for any triangle. When we start with a non-right triangle the theorem works by not giving equality. Of course the Law of Cosines gives the squared side of any triangle given the opposite angle and other two sides.

### How do you solve a2 b2 c2?

How do you use a2 b2 c2? a2 + b2 = c2 Subtract 2ab from both sides. The last equation, a2 + b2 = c2, is called the Pythagorean Theorem. We say βThe sum of the squares of the legs of a right triangle equals the square of its hypotenuse.β

### What type of triangle does the Pythagorean Theorem apply to?

Note that the Pythagorean Theorem only works with right triangles. You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle's other two sides, called the legs.

### How to find the length of a triangle using the Pythagorean equation?

You might recognize this theorem in the form of the Pythagorean equation: If you know the length of any 2 sides of a right triangle you can use the Pythagorean equation formula to find the length of the third side. This calculator solves the Pythagorean Theorem equation for sides a or b, or the hypotenuse c.

### How to calculate the height of a right triangle?

The Pythagorean Theorem solution works on right triangles, isosceles triangles, and equilateral triangles. It will not work on scalene triangles! The formula for the area of a triangle is 1 2 base × height 1 2 b a s e × h e i g h t, or 1 2 bh 1 2 b h. If you know the area and the length of a base, then, you can calculate the height.

### What is the Pythagorean theorem for right triangles?

Pythagorean Theorem for Right Triangles. a = side leg a. b = side leg b. c = hypotenuse. A = area.

### How to calculate the value of X using the Pythagorean theorem?

Use the Pythagorean theorem to calculate the value of X. Round your answer to the nearest hundredth. Remember our steps for how to use this theorem. This problems is like example 2 because we are solving for one of the legs . Identify the legs and the hypotenuse of the right triangle . The legs have length '10' and 'X'. The hypotenuse is 20.
