How do you find the height of a triangle if you know the side lengths?

How do you find the height of a triangle if you know the side lengths?

The Pythagorean Theorem states that for any right triangle with sides of length a and b, and hypotenuse of length c: a2 + b2 = c2. We can use this theorem to find the height of our equilateral triangle!

How do you find the height of a triangle 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 = 13.20 ( t o 2 d . p . ) We now know the height of the triangle and can use this to go back and find the area of the isosceles triangle.

How do you calculate the altitude of a triangle?

It’s using an equation called Heron’s formula that lets you calculate the area if given sides of the triangle. Then, once you know the area, you can use the basic equation to find out what is the altitude of a triangle: Heron’s formula: area = 0.25 * √((a + b + c) * (-a + b + c) * (a – b + c) * (a + b – c))

How do you calculate the length of a triangle?

Formula for Length of Triangle. Triangle contains three face and three vertices. Sum of interior angle of the all type of triangle is 180 degree. The following diagram is declaring the length of the triangle. Length formula for triangle. The length formula for triangle is L = 2a / b. a is area of the triangle.

What is the equation for a triangle?

A triangle is one of the most basic shapes in geometry. The best known and the simplest formula, which almost everybody remembers from school is: area = 0.5 * b * h, where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

What is the height of an equilateral triangle?

An equilateral triangle has a side of 16 units. What is the height of this equilateral triangle. 16/2=8√3 units or 13.856 units. The height of an equilateral triangle is 10 units.
