Guided Notes
3 key concepts
- 1
A triangle is a shape with three sides and three angles, and the sum of its interior angles is always 180 degrees.
- 2
Triangles can be classified by their angles (right, acute, obtuse) or by their sides (equilateral, scalene, isosceles).
- 3
The sum of the interior angles of a quadrilateral is 360 degrees, which can be shown by dividing it into two triangles.
