How many degrees are inside a Triangle? - YouTube
It's not too tough of a name to remember since the beginning of equilateral sounds like the word equal, and the word lateral means "side. " In the middle triangle, we can see that two of the sides are the same length and measure 8 cm while the third is 9 cm. When two of the sides of a triangle are the same it's called an isosceles triangle. It's a hard one to spell, but an easy one to recognize! In our last triangle, none of the sides have the same length, so this is called a scalene triangle. While you often see these three types of triangles identified by the lengths of their sides, they can also be categorized by their angles. It works exactly the same way: When all the angles are the same 60 degrees, it's an equilateral triangle. Technically, it's called an equiangular triangle but they're exactly the same thing because all equilateral triangles are also equiangular triangles. When two of the angles are the same it's an isosceles triangle. And when none of the angles are the same it's a scalene triangle.
Now everyone here is reporting 180 degrees and I second that. My answer would aslo be 180% cos I was taught at school that a triangle is 180 degrees. A circle is 360 degree and I understand that. A square has four 90 degree perpendicular angles. so a square should be 90x4 = 360 degrees. The triangle has three 45 degree angles. So that should be 3x45 = 135 degrees for a Triangle.. Can anyone explain to me how does a Triangle have 180 degree? Well you may be thinking that I am the dumbest person on earth but I think I don't have my fundamental correct. Can anyone help me to get my Fundas right 180 Degrees in a triangle, 360 in a circle. 180 degrees in any triangle 180 degrees let it be any triangle Anyways, Further There are three classifications of triagles on the basis of angles If one angle is more than 90 degreed, then the triangle is Obtuse Angled Triangle If One angle in the triangle is 90 degreed, then it is called Right Angled Triangle And if all angles are less than 90 then the triangle is called acute angled triangle!
The sum of the interior angles of a triangle are equal to 180 o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180 o. Example: How many degrees are in the third angle of a triange whose other two angles are 40 o and 65 o? Answer: 180 o - 40 o -65 o = 75 o
In other words, they're the kind of angles we've been talking about all along. The exterior angles of a triangle are all the angles between one side of the triangle and the line you get by extending a neighboring side outside the bounds of the triangle. If you think about it, you'll see that when you add any of the interior angles of a triangle to its neighboring exterior angle, you always get 180 0 —a straight line. How many degrees is a triangle? Which brings us to the main question for today: Why is it that the interior angles of a triangle always add up to 180 0? As it turns out, you can figure this out by thinking about the interior and exterior angles of a triangle. To see what I mean, either grab your imagination or a sheet of paper because it's time for a little mathematical arts-and-crafts drawing project. Start by drawing a right triangle with one horizontal leg, one vertical leg, and with the hypotenuse extending from the top left to the bottom right. Now make a copy of this triangle, rotate it around 180 0, and nestle it up hypotenuse-to-hypotenuse with the original (just as we did when figuring out how to find the area of a triangle).
Just remember that acute angles are less than 90 degrees. This one is easy to remember, since "cute" things are often small, like puppies and kittens. We can see that in the middle triangle the largest angle is exactly 90 degrees. You might remember that a 90-degree angle is a right angle, so this triangle is a right triangle. Finally, in the triangle on the right, the largest angle is 117 degrees. Because this is more than 90 degrees, this is an obtuse angle, so we call this triangle an obtuse triangle. That's all there is to it for these three types. We just find the largest angle and the name of the triangle will correspond to the name of that angle. Our second set of triangles is categorized by how many of the sides have the same length. Here are three triangles with the lengths of the sides included: In the triangle on the left, we can see that all three sides are the same length and measure 9 centimeters. A triangle like this one where all the sides are the same is called an equilateral triangle.

Q Which angles are equal in an isosceles triangle? A The two angles that are equal in an isosceles triangle are the two base angles. An isosceles triangle has two equal sides that meet at a point. The angle made by these two lines meeting is the unique angle. The angles formed by the bases of these lines and a third, unique side, are the two equal angles, called base angles. Q What are the characteristics of an equilateral triangle? A An equilateral triangle is a triangle that has three equal sides and three equal angles. Practice Questions Question #1: What kind of triangle is this? Acute Equilateral Isosceles Scalene Show Answer Answer: The correct answer is scalene. A scalene triangle is a triangle with no equivalent sides. Hide Answer Question #2: What kind of triangle is this? Obtuse isosceles Acute isosceles Acute scalene Obtuse scalene Show Answer Answer: The correct answer is acute isosceles. An isosceles triangle has two congruent sides (as shown by the two tick marks) and one unique side.
