Maybe this is the wrong video to post this question on, but I'm really curious and I couldn't find any other videos on here that might match this question. So the first categorization right here, and all of these are based on whether or not the triangle has equal sides, is scalene. Can a acute be a right to. Then the other way is based on the measure of the angles of the triangle.

I dislike this(5 votes). Created by Sal Khan. So for example, if I have a triangle like this, where this side has length 3, this side has length 4, and this side has length 5, then this is going to be a scalene triangle. Want to join the conversation? So for example, a triangle like this-- maybe this is 60, let me draw a little bit bigger so I can draw the angle measures. Classifying triangles worksheet answer key. A right triangle has to have one angle equal to 90 degrees. An isosceles triangle can have more than 2 sides of the same length, but not less. Now an equilateral triangle, you might imagine, and you'd be right, is a triangle where all three sides have the same length. Maybe this angle or this angle is one that's 90 degrees. But on the other hand, we have an isosceles triangle, and the requirements for that is to have ONLY two sides of equal length. What is a reflex angle? The only requirement for an isosceles triangle is for at minimum 2 sides to be the same length.

Equilateral: I'm always equal, I'm always fair! They would put a little, the edge of a box-looking thing. I've asked a question similar to that. So by that definition, all equilateral triangles are also isosceles triangles. No, it can't be a right angle because it is not able to make an angle like that. Maybe this has length 3, this has length 3, and this has length 2.

So for example, this one right over here, this isosceles triangle, clearly not equilateral. A perfect triangle, I think does not exist. My weight are always different! What type of isosceles triangle can be an equilateral. Equilateral triangles have 3 sides of equal length, meaning that they've already satisfied the conditions for an isosceles triangle. Now an isosceles triangle is a triangle where at least two of the sides have equal lengths. 4-1 practice classifying triangles answer key. An isosceles triangle can not be an equilateral because equilateral have all sides the same, but isosceles only has two the same. So let's say a triangle like this. Now you might say, well Sal, didn't you just say that an isosceles triangle is a triangle has at least two sides being equal. The first way is based on whether or not the triangle has equal sides, or at least a few equal sides.

A reflex angle is an angle measuring greater than 180 degrees but less than 360 degrees. And a scalene triangle is a triangle where none of the sides are equal. Why is an equilateral triangle part of an icoseles triangle. Or if I have a triangle like this where it's 3, 3, and 3. Notice all of the angles are less than 90 degrees. 4-1 classifying triangles answer key of life. So for example, this would be an equilateral triangle. So it meets the constraint of at least two of the three sides are have the same length. 25 plus 35 is 60, plus 120, is 180 degrees. Now down here, we're going to classify based on angles. A triangle cannot contain a reflex angle because the sum of all angles in a triangle is equal to 180 degrees.

It's no an eqaulateral. But not all isosceles triangles are equilateral. Can it be a right scalene triangle? If this angle is 60 degrees, maybe this one right over here is 59 degrees. Are all triangles 180 degrees, if they are acute or obtuse? Notice, they still add up to 180, or at least they should. None of the sides have an equal length. All three sides are not the same. They would draw the angle like this. An equilateral triangle has 3 equal sides and all equal angle with angle 60 degrees.

Absolutely, you could have a right scalene triangle. What I want to do in this video is talk about the two main ways that triangles are categorized. Wouldn't an equilateral triangle be a special case of an isosceles triangle? Or maybe that is 35 degrees. Notice, this side and this side are equal. An equilateral triangle would have all equal sides. That is an isosceles triangle. Have a blessed, wonderful day! In this situation right over here, actually a 3, 4, 5 triangle, a triangle that has lengths of 3, 4, and 5 actually is a right triangle. Maybe you could classify that as a perfect triangle!

I've heard of it, and @ultrabaymax mentioned it. And this is 25 degrees. Isosceles: I am an I (eye) sosceles (Isosceles). An equilateral triangle has all three sides equal? That's a little bit less. An equilateral triangle has all three sides equal, so it meets the constraints for an isosceles.
