That is an equilateral triangle.
Having two dashes on a triangle is common notation in arithmetic, specifically geometry. Two dashes mean that there is one dash each on two different lines of the triangle, and this indicates that the two lines are of equal length. This also means that the triangle is an isosceles triangle.
It has 3 sides It has 3 exterior angles that add up to 360 degrees It has 3 interior angles that add up to 180 degrees It has a perimeter which is the sum of its 3 sides It has an area which is: 0.5*base*perpendicular height It has no diagonals It will tessellate It can be a scalene triangle having 3 different acute angles It can be an obtuse triangle having 1 obtuse angle and 2 different acute angle It can be a right angle triangle having a 90 degree angle and 2 acute angles It can be an isosceles triangle having 2 equal sides and 2 equal acute angles It can be an equilateral triangle having 3 equal sides and 3 equal 60 degree angles It is subject to the rules of trigonometry
Angles having the same measure in degrees irrespective of how large the arms of one are compared to another are said to be congruent angles
They are said to be congruent

That is an equilateral triangle.
A triangle having 3 congruent sides is an equilateral triangle
A three sided closed figure. It is one of the basic shapes of geometry.
This are called congruent angles. For example, In an isosceles triangle, the two angles which are opposite to the sides that have the same length, have the same measurements. They are called the base angles of the triangle. When each of them is 45 degree, the triangle is also a right triangle, since the other angle is 90 degree.
An isosceles triangle has at exactly two congruent sides, while an equilateral triangle has all equal sides.--Korean Swag

An equilateral triangle is a triangle with all sides & angles having the same measure.An isosceles triangle is a triangle with 2 sides & angles measuring the same, leaving one angle/side to be different.A scalene triangle is a triangle with no sides and/or angles measuring the same length.

By having congruent triangles the ramps up which I drive my car are equal and the whole experience is safe. So very significant.
yes because a square is, by definition, a shape having 4 ninety degree angles, and four congruent sides
Scalene. as opposed to equilateral ( all sides equal) or having two sides equal.
