4Section 4.1 Triangles and Angles
- Are all three of these shapes triangles?
- Using these examples come up with a clear
definition of a triangle.
5BASIC OF A Triangle
- THE BASICS
- 3 sides
- 3 angles (at vertices)
WE CAN CLASSIFY ALL TRIANGLES BASED ON ITS SIDES
AND ITS ANGLES
6Classify that Triangle
- BY ITS SIDES
- Equilateral
- 3 congruent sides
- Isosceles
- 2 congruent sides
- Scalene
- no congruent sides
7Classify that Triangle
- BY ITS ANGLES
- Equilangular
- 3 congruent angles
- Acute
- 3 acute angles
- Right
- 1 right (90) angle
- Obtuse
- 1 obtuse angle
8Parts of any triangles
- In the triangle at left, points A, B, and C are
examples of what?
Side opposite ?A
Adjacent Side
Vertices (vertex)
Adjacent Side
Two sides are adjacent if they share the same
vertex. The other side is considered opposite
that vertex (angle).
