Are sides of a triangle always equal?
An equilateral triangle has all sides equal in length and all interior angles equal.
What should the sides of a triangle equal?
The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. See the side lengths of the acute triangle below. The sum of the lengths of the two shortest sides, 6 and 7, is 13.
What do the three sides of a triangle have to equal?
Equilateral triangles An equilateral triangle has three equal sides and three equal angles (which are each 60°). Its equal angles make it equiangular as well as equilateral.
What is a triangle with all sides different?
A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene.
Can a triangle have 4 sides?
A triangle is a primitive form of geometry (polygon) that can only have three sides in its simplest form.
What is Sohcahtoa?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2) (3)
Do triangles have 3 or 4 sides?
The triangle has three (3) sides. The triangle is a polygon that contains three sides and three inner angles and three vertices. A triangle is a primitive form of geometry (polygon) that can only have three sides in its simplest form.
What is the formula for determining sides of a triangle?
How to find the sides of a right triangle if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √ (c² – if leg b is unknown, then b = √ (c² – a²) for hypotenuse c missing, the formula is c = √ (a² + b²)
What triangle has two equal sides and one longer one?
Yes, the hypotenuse is always the longest side, but only for right angled triangles. For isosceles triangles, the two equal sides are known as the legs, while in an equilateral triangle all sides are known simply as sides.
How many triangles have at least two equal sides?
An isosceles triangle has two equal sides and one side that is not equal. An equilateral triangle has 3 equal sides. In an acute triangle, all of the angles will measure less than 90 degrees. A right triangle will always have one 90-degree angle.
What is triangle that has two equal sides called?
An Isosceles Triangle is a triangle that has two equal angles and sides. A triangle with 2 equals sides is called a Isosceles triangle. That’s an isosceles triangle.
