i need help please
You sure do.
An equilateral triangle has THREE equal sides.
Triangle A
To determine which of the given triangles is an equilateral triangle, we need to check if all three sides of the triangle are of equal length.
Let's examine each triangle:
- Triangle A has three sides measuring 7 units each. Since all three sides are equal in length, Triangle A is an equilateral triangle.
- Triangle B has two sides that are equal, but the base is longer. Therefore, Triangle B is not an equilateral triangle.
- Triangle C has no sides of equal length, so it cannot be an equilateral triangle.
- Triangle D has sides of length seven, three, and six. Since all three sides have different lengths, Triangle D is not an equilateral triangle.
Therefore, the only triangle that is an equilateral triangle from the options given is Triangle A.
