Step 1: Set the expressions labeling the angles equal to each other. Step 2: Isolate the variable on one side of the equation using the additive and multiplicative properties of equality. Step 3: If the measurement of the angles is needed, substitute the result from step 2 into the expr...

Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees. ...
When a line (called a transversal) intersects a pair of lines, alternate interior angles are formed on opposite sides of the transversal. If the pair of lines areparallelthen the alternate interior angles are equal to each other. TheAlternate Interior Angles Theoremstates that ...
Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees. Read Vertical & Complementary Angles | Definition &...
These angles are supplementary, meaning that they add up to 180 degrees. They are also congruent, meaning that they are equal in measure. The two alternate exterior angles are always congruent to each other, regardless of the type of lines that are crossed....

PR can be indicated by angles R_min and R_max and the angular extend of PR is between R_max and R_min. Typically, the angles R_max and L_max are less than 90 degrees from the normal 0 due to the thickness of the display; and the angles are equal to each other to have symmetri...
