# What is the intersection of altitudes called?

Definition: an altitude is a segment from the vertex of a triangle to the opposite side and it must be perpendicular to that segment (called the base). As the picture below shows, sometimes the altitude does not directly meet the opposite side of the triangle.

orthocenter

Also, what is an example of altitude? Definition: an altitude is a segment from the vertex of a triangle to the opposite side and it must be perpendicular to that segment (called the base). As the picture below shows, sometimes the altitude does not directly meet the opposite side of the triangle.

Consequently, is altitude always 90 degree?

In geometry, the altitude is a line that passes through two very specific points on a triangle: a vertex, or corner of a triangle, and its opposite side at a right, or 90degree, angle. This is because it touches a vertex of the triangle.

What is the formula for altitude of a right triangle?

Reversing that, the height of any triangle is it’s area divided by half its base. Multiply the two sides that make up the 90° angle and divide by two to get the area of the triangle. Then divide that area by half the hypotenuse to get the height to the hypotenuse. WOW!

### What is the point where the 3 medians of a triangle meet?

A centroid of a triangle is the point where the three medians of the triangle meet. A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle. The centroid is also called the center of gravity of the triangle.

### What is difference between altitude and perpendicular?

1 Answer. Segment joining a vertex to the mid-point of opposite side is called a median. Perpendicular from a vertex to opposite side is called altitude. A Line which passes through the mid-point of a segment and is perpendicular on the segment is called the perpendicular bisector of the segment.

### What is the Orthocentre of Triangle?

The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side. There are therefore three altitudes in a triangle.

### What is a perpendicular bisector of a triangle?

The perpendicular bisector of a side of a triangle is a line perpendicular to the side and passing through its midpoint. The three perpendicular bisectors of the sides of a triangle meet in a single point, called the circumcenter .

### Where do medians intersect triangles?

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle’s centroid.

### Do altitudes bisect angles?

since congruent angles are angles of equal measure. The altitude to the base of an isosceles triangle bisects the vertex angle. The altitude to the base of an isosceles triangle bisects the base.

### Are all altitudes of a triangle equal?

all the three altitudes are equal. BC ,CA and AB respectively. (2) If any two sides of a triangle are equal , two altitudes are equal.

### What is the point of concurrency?

A point of concurrency is where three or more lines intersect in one place. Incredibly, the three angle bisectors, medians, perpendicular bisectors, and altitudes are concurrent in every triangle.

### What is the formula for altitude?

Altitude in terms of the sides This follows from combining Heron’s formula for the area of a triangle in terms of the sides with the area formula (1/2)×base×height, where the base is taken as side a and the height is the altitude from A.

### What is Earth’s altitude?

As a general definition, altitude is a distance measurement, usually in the vertical or “up” direction, between a reference datum and a point or object. Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.

### Is an altitude always perpendicular to the opposite side?

The altitude of a triangle is a line from a vertex to the opposite side, that is perpendicular to that side, as shown in the animation above. A triangle therefore has three possible altitudes. The altitude is the shortest distance from a vertex to its opposite side.

### What is median and altitude of triangle?

Median – A line segment joining a vertex of a triangle with the mid-point of the opposite side. Altitude – A line segment joining a vertex of a triangle with the opposite side such that the segment is perpendicular to the opposite side.

### What is the altitude of isosceles triangle?

The unequal side of an isosceles triangle is usually referred to as the ‘base’ of the triangle. When the 3rd angle is a right angle, it is called a “right isosceles triangle”. The altitude is a perpendicular distance from the base to the topmost vertex.
