how to label a trinagle

There are two rules around how to label a triangle and the main ones are uppercase and lowercase letters 

The first rule is that when labelling a triangle all of the angles on the inside of the triangle must be a capital letter. 

• All of the letters that stand for the length of the sides of triangles must be labelled with a lowercase letter.
• You can not have the same letter next to each other. usually, the letters will be opposite on the opposite side of each other  

You have to use these rules because when you are doing an equation with two lowercase letters, it can get confusing because you don't know what you are talking about.

  In Math, all triangles are 180° 

Right angle triangle.

Acute triangle.

Equilateral triangle.

Isosceles triangle.

They have three points on the end of them

all triangles have three sides

They have three connections.

R.A.T triangles = C2 = A2 + B2

Tangent is the trigonometric function that is equal to the ratio of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right-angled triangle.

Cosine is the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.

Since the trigonometric function is equal to the ratio of the side opposite a given angle (in a right-angled triangle) to the hypotenuse.

Hypotenuse: the hypotenuse is the longest side of the right triangle, and this is the opposite side of the right angle.

Legs: the legs are always shorter than the hypotenuse. The legs create the "right" angle in the triangle. The legs are placed on either side of the triangle. All triangles have to have 2 legs.

Theorem: The theorem is a formula or it could be a theory that can be proved.

R.A.T: R.A.T stands for Right Angle Triangle.Pythagoras's theorem

all triangles are 180° if it is greater than 180° it wasn't a triangle.

this is Pythagoras
