Given the size of the 3 sides of the triangle, is it an equilateral triangle?
To determine if the triangle is equilateral, we need to verify if all three sides are of equal length. The given side lengths are:
An equilateral triangle is one in which all sides are equal. Thus, we check the equality:
.
Substituting the given values, we have:
Since all three sides of the triangle are indeed equal, we conclude that the triangle is an equilateral triangle.
Therefore, the correct answer is Yes.
Yes
In a right triangle, the side opposite the right angle is called....?
That would make it an isosceles triangle, not equilateral! An isosceles triangle has exactly two equal sides, while equilateral requires all three sides to be equal.
If all sides are equal, the angles are automatically equal too (each 60°). But for identification, just check the side lengths - that's the quickest method!
These are all equal! 6.0 = 6 = 6.00 - different decimal representations don't change the value. The triangle is still equilateral.
In math problems with exact values like this, they must be exactly equal. In real-world measurements, very small differences might be due to measurement error.
No! Side lengths must always be positive numbers. Negative lengths don't make sense for actual distances in geometry.
