For a triangle to be equilateral, it must also have equal angles. For example, if the triangle is a right-angle triangle and the two sides that meet to make the right angle are the same length, then the 3rd side would be longer than those two. Difference between velocity and a vector? So, by that definition alone, an equilateral triangle is always an isosceles triangle with the 3rd side happens to be of the same length as the other 2. How would you show that a triangle with vertices (13,-2), (9,-8), (5,-2) is isosceles? has a right angle. (Because 90 + 90 = 180, which is the sum of all the angles in any triangle). Just because you have more than what you need, doesn't mean you aren't that too.

Step-by-step explanation: To Find :An equilateral triangle is a right triangle. We know that an equilateral triangle has three sides equal. Therefore, a equilateral triangle could be isoceles, but an isoceles triangle cannot be an equlateral triangle. So to summarize a right-angled triangle is sometimes isosceles on the condition that one of its angles (apart from the right-angle) is 45deg ( because then the other will also be 45deg) Good luck! In an isosceles triangle, two sides are the same length. An equilateral triangle has three sides equal in length whereas an isosceles triangle only has two sides equal in length. intersects exactly two other sides of the polygon.
