What is the definition of the base of a triangle?

What is the definition of the base of a triangle?

Answer: The bottom line of a triangle is the base of the triangle, and it can be one of the three sides of the triangle. In a triangle, one side is a base side and the remaining two sides can be the height or the hypotenuse side.

What does base mean in geometry?

In geometry, a base is a side of a polygon or a face of a polyhedron, particularly one oriented perpendicular to the direction in which height is measured, or on what is considered to be the “bottom” of the figure.

Which part of triangle is base?

The base is the side of a triangle which is considered to be the bottom, while the height of a triangle is the perpendicular line dropped onto its base from the vertex opposite to the base.

What is base area math?

In geometry, the bottom of a three-dimensional object is called a base – if the top of the solid is parallel to the bottom it is also called a base. You can find the area of a base by using the formula for the area of that shape.

What is base of an object?

Definition: The bottom of a shape, solid or three dimensional object. The base is what the object ‘rests’ on. The base is the surface of the object that is stands on or it is the bottom line. Examples: The bottom of the triangular based prism is considered the base.

How many bases does triangle have?

The altitude of a triangle is the perpendicular from the base to the opposite vertex. (The base may need to be extended). Since there are three possible bases, there are also three possible altitudes. The three altitudes intersect at a single point, called the orthocenter of the triangle.

How do you find the base of a figure?

How to Calculate the Base of a Shape.

What makes a base a base?

A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way. Because the base “soaks up” hydrogen ions, the result is a solution with more hydroxide ions than hydrogen ions. This kind of solution is alkaline.

What is the base of an object?

What is the formula to find the base of a triangle?

The most common formula for finding the area of a triangle is K = ½ bh, where K is the area of the triangle, b is the base of the triangle, and h is the height.

How do you know what the base of a triangle is?

The base of a triangle can be any one of the three sides, usually the one drawn at the bottom. You can pick any side you like to be the base. Commonly used as a reference side for calculating the area of the triangle. In an isosceles triangle, the base is usually taken to be the unequal side.

How do you find the base and height of a triangle?

Because you can draw a right triangle inside any triangle, you can also use trigonometric identities to find the height of a triangle. If you know the angle between the height and the hypotenuse of the triangle, you can set up the equation tan(a) = x / b_, where a is the angle, x is the height and b_ is half the base.

Can a triangle have the same base and area?

The area of a triangle is half of the product of the base and the perpendicular height, so given the base and the area, the height is fixed. But there are only four possible triangles with this height; they are reflections of each other in the axes of the ellipse and so congruent.
