What is the best definition of an equilateral triangle?
In geometry, an equilateral triangle is a triangle whose all three sides are of equal length. The sides of an equilateral triangle are congruent.
What is an equilateral triangle simple definition?
An equilateral triangle is a triangle with all three sides of equal length , corresponding to what could also be known as a “regular” triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal.
How do you describe an equilateral triangle?
In geometry, an equilateral triangle is a triangle that has all its sides equal in length. For example, a triangle with its three sides equal to 5cm is an equilateral triangle. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure.
What is meaning by equilateral?
1 : having all sides equal an equilateral triangle an equilateral polygon — see triangle illustration. 2 : having all the faces equal an equilateral polyhedron.
Which is the best definition of a triangle?
A triangle is a three-sided polygon that closes in a space. It uses lines, line segments or rays (in any combination) to form the three sides. When three sides form and meet, they create three vertices, or corners. The corners inside the triangle are interior angles.
What does equilateral triangle look like?
An equilateral triangle is a 3-sided polygon (enclosed shape) that whose sides are all congruent (equal in length). An equilateral triangle also has 3 congruent angles, all 60˚ in measure.
What is defined as a triangle?
1 : a flat geometric figure that has three sides and three angles. 2 : something that has three sides and three angles a triangle of land. 3 : a musical instrument made of a steel rod bent in the shape of a triangle with one open angle.
What is the longest side of a right triangle called?
hypotenuse
We define the side of the triangle opposite from the right angle to be the hypotenuse, h. It is the longest side of the three sides of the right triangle. The word “hypotenuse” comes from two Greek words meaning “to stretch”, since this is the longest side.
