Characteristics of Triangles
Triangles are important geometric shapes. They all have 3 sides, 3 interior angles and 3 vertices (corners).

Its second name is based on the relationship of its angles. A triangle will either have one right angle, one obtuse angle, or three acute angles

- A right angle (90˚).
- Two legs (These are the sides adjacent to the right angle).
- A hypotenuse (The longest side opposite the right angle).
