What is the triangle in math called?
A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.
How do you find the geometry of a triangle?
The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
What are the 3 types of triangles?
Let’s start with the three types of triangles that are categorized by the measure of their largest angle. These are the acute, right, and obtuse triangles.
What is triangle simple?

What is triangle angle?
The angle of a triangle is the space formed between two side lengths of a triangle. A triangle contains interior angles and exterior angles. Interior angles are three angles found inside a triangle. The interior angles are a, b and c, while exterior angles are d, e, and f.
What number does a triangle equal in math?
Triangular numbers are a type of figurate number, other examples being [ [square nu n th triangular number is the number of dots in the triangular arrangement with n dots on a side, and is equal to the sum of the n natural numbers from 1 to n.
How do you calculate triangles?
Use the equation for the area of a triangle. You can find the area of any triangle when you know that it is equal to one half the base times height of the triangle. The equation is A = (1/2)bh, where b (base) is the horizontal length of the triangle and h (height) is the vertical length of the triangle.
How to calculate triangle?
A triangle is determined by 3 of the 6 free values, with at least one side. Fill in 3 of the 6 fields, with at least one side, and press the ‘Calculate’ button. (Note: if more than 3 fields are filled, only a third used to determine the triangle, the others are (eventualy) overwritten 3 sides
What is the formula for a triangle?
Area = 1/2 × Base × Height
