4.1 Triangles & Angles

- Is a figure formed by three segments
- Joining three noncollinear points….it has
- Sides…..
- And Angles.

- Scalene (no sides equal)
- Isosceles (as least 2 sides equal)
- Equilateral (3 congruent sides)

- Acute (3 acute angles)
- Right (1 right angle)
- Obtuse (1 obtuse angle)
- Equiangular (3 congruent angles)

- Vertex A

- The sum of the interior angles of a triangle is 180 degrees.

- The measure of an exterior angle of a triangle is equal to the sum of the two nonadjacent interior angles.

- Is a statement that can be proved easily using a theorem
- Think of it as a mini-theorem.

- The acute angles of a right triangle are complementary.
