# How do you find the altitude of a triangle of a right triangle?

## How do you find the altitude of a triangle of a right triangle?

The formula to calculate the altitude of a right triangle is h =√xy. where ‘h’ is the altitude of the right triangle and ‘x’ and ‘y’ are the bases of the two similar triangles formed after drawing the altitude from a vertex to the hypotenuse of the right triangle.

What is the hypotenuse of ∆ ABC?

In any right-angled triangle, ABC, the side opposite the right-angle is called the hypotenuse. Here we use the convention that the side opposite angle A is labelled a. The side opposite B is labelled b and the side opposite C is labelled c.

### Is CD The geometric mean of AD and BD explain?

1. Segment CD is the geometric mean of segments AD and BD. In other words, the altitude is the geometric mean of the two segments of the hypotenuse.

What is the right angle altitude theorem?

The right triangle altitude theorem or geometric mean theorem is a result in elementary geometry that describes a relation between the altitude on the hypotenuse in a right triangle and the two line segments it creates on the hypotenuse. It states that the geometric mean of the two segments equals the altitude.

#### How many altitudes are there in a right triangle?

three altitudes
Answer: Three An altitude of a triangle is a line segment that starts from the vertex and meets the opposite side at right angles. A triangle has three altitudes- one end is at the vertex and the other on the opposite side. An altitude is also known as the height of the triangle.

What is the geometric mean of the altitude BD?

The measure of the altitude drawn from the vertex of the right angle to the hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse. Hence BD is the geometric mean of AD and DC.

## How do you find C in a right triangle?

In a right triangle with cathetus a and b and with hypotenuse c , Pythagoras’ theorem states that: a² + b² = c² . To solve for c , take the square root of both sides to get c = √(b²+a²) . This extension of the Pythagorean theorem can be considered as a “hypotenuse formula”.

How do you find the altitude of a right triangle with 3 sides?

A right triangle is a triangle with one angle equal to 90°. Two heights are easy to find, as the legs are perpendicular: if the shorter leg is a base, then the longer leg is the altitude (and the other way round). The third altitude of a triangle may be calculated from the formula: hᶜ = area * 2 / c = a * b / c.

### Is an altitude in triangle ABC?

The line opposite the vertex where the altitude is perpendicular to is the base. In △ABC above, BD is an altitude. It contains vertex B and is perpendicular to AC, which is the base. In the above △ABC, BD, CE, and AF are all altitudes of the triangle.

How many altitudes does a triangle have a 1 B 3 C 6 D 9?

3 altitudes
A triangle has 3 altitudes.

#### What is the altitude of a hypotenuse?

In a right triangle, the altitude from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of the lengths of the two segments of the hypotenuse. a alt AO CD.

Does a triangle have 3 altitudes?

Altitude(s) of a Triangle. An altitude of a triangle is a segment from a vertex of the triangle, perpendicular to the side opposite that vertex of the triangle. Since all triangles have three vertices and three opposite sides, all triangles have three altitudes.
