22. Geometry theorems

23. Geometry The sum of the angles of a triangle is always 180 o. A C B m└A + m└B + m└C = 180

24. Geometry Each exterior angle of a triangle is equal to the sum of the remote interior angles. A C B m└D = m└A + m└C D

25. Geometry Larger sides are opposite larger angles.

26. Geometry Smaller sides are opposite smaller angles.
