A. Vertical and Adjacent Angles
Angles that are across from each other, or vertical angles, are congruent .
(Same measure different location). Angles that share a common vertex or
side are called adjacent angles. If they form a straight line, they add up to
180°. We can set the two parts equal to each other if they are vertical or add
them together to get 180° if they are adjacent and solve for x to find the
missing angles.
Vertical Examples:
Adjacent Examples:
B. Sides In a Triangle
In a triangle, the sum of any two sides must be greater than the third side.
Examples:
Can any of these sets of sides form a triangle?
