Step-by-step explanation:
1) A triangle has three sides.
2) The sum of the three interior angles of a triangle is always 180°.
3) The sum of the length of two sides of a triangle is always greater than the length of the third side.
4) A triangle with vertices P, Q, and R is denoted as △PQR
5) The area of a triangle is equal to half of the product of its base and height.
6) To classify triangles according to their angles, we measure each of its interior angles. Triangles can be classified by angles, as:
→ Acute Triangle
→ Right Triangle
→ Obtuse Triangle
side AB , side BC , side AC
angle ABC , angle BCA , angle BAC
