Interior Angle for Dummies

Interior Angle is a term that we use in math to talk about angles that are inside a shape. Now, before we dive into the fancy math terminologies, let me ask you a question. Have you ever played with building blocks or legos? Imagine you have a big triangle made out of legos. Now, if you take your finger and place it inside the triangle, the angle that your finger makes with the two sides of the triangle is what we call an interior angle. It's like you are peeking inside the triangle and measuring the angle you see.

In simple terms, an interior angle is just an angle inside a shape like a polygon. It's like looking inside the shape and measuring the corner you find. Imagine you are inside a room with four walls, and you are sitting in one corner of the room. The angle you make with the two walls that meet at that corner is the interior angle of that corner. It's the angle you see when you are "inside" the shape.

Now, there's a bit more to it. You see, shapes have different numbers of sides, right? Some have three sides like a triangle, some have four sides like a square, and some shapes can have many more sides. So, when we talk about interior angles, we focus on the specific shape we are dealing with.

For example, in a triangle, which has three sides, there are three interior angles. The sum of all the interior angles in a triangle is always 180 degrees. So, if you add up all the angles you see when you look inside a triangle, it will always be 180 degrees. It's like a secret code that triangles follow.

Now, let's take a look at a square. A square has four sides, right? So, how many interior angles do you think a square has? You got it, four! And do you know what the sum of all the interior angles of a square is? It's 360 degrees! So, when you add up all the angles you see inside a square by peeking from each corner, you will always get 360 degrees.

In summary, an interior angle is just an angle that is inside a shape. It's like peeking inside a shape and measuring the angle you see. Different shapes have different numbers of sides and, therefore, different numbers of interior angles. And the sum of all the interior angles in a shape is always the same for that particular shape. It's like a secret code that each shape follows.

So, now that we've explored the world of interior angles, I hope you have a clear understanding of what they are and how they relate to different shapes!
