What is a Triangle?
- A triangle is a shape with three sides and three angles.
- It has three must-haves: 3 sides, 3 angles, and all angles add up to 180 degrees.
Types of Triangles
- Triangles are categorized by the length of their sides and the size of their angles.
- There are three categories of triangles based on the length of their sides:
- Equilateral: All sides are equal, and all angles are equal.
- Isosceles: Two sides are equal, and two angles are equal.
- Scalene: No sides are equal, and no angles are equal.
Angles
- An angle is the space between two lines that connect and form a point.
- Angles are measured in degrees, which indicate how big or small an angle is.
- There are three types of angles:
- Acute: Angles less than 90 degrees.
- Obtuse: Angles greater than 90 degrees.
- Right: Angles equal to 90 degrees.
- A triangle can be categorized by both its sides and angles, e.g., equilateral and acute, or scalene and obtuse.
