In geometry, a transversal is a line that passes through two lines in the same
plane at two ... Further, if the angles of one pair are congruent, then the angles of
each of the ... angle on a triang...
As can be seen from the figure above, when two lines intersect, four angles are
formed. Each opposite pair are called vertical angles and are always congruent.
In geometry, certain pairs of angles can have special relationships. ... Vertical
angles always have equal measures. ? ... Alternate interior angles are congruent
to each other if (and only if) the two lines intersected by the transversal are
When two lines intersect they form two pairs of opposite angles, A + C and B + D.
... Vertical angles are always congruent, which means that they are equal.
If two congruent angles form a linear pair, the angles are right angles. If two
congruent angles ... are a linear pair). Vertical angles are always equal in
Angles between two parallel lines that are cut by a third line. ... Recall that all
pairs of vertical angles are congruent. Supplementary pairs: angle 1 and angle 2
Congruent Angles: Definition & Examples .... Vertical angles are a pair of non-
adjacent angles formed when two lines intersect. We see ... In addition, angles
that form a linear pair are also supplementary, so their sum is always 180
They are defined as a pair of nonadjacent angles formed by only two intersecting
lines. They are known as 'Kissing Vs' and always have congruent measures.
Vertical angles are pairs of angles formed by two intersecting lines. ... in four
corresponding pairs that have the same measure, so therefore are congruent.
Theorem: Vertical angles are always congruent. ... 1 and ∠ 2 form a linear pair,
so by the Supplement Postulate, they are supplementary. That is,. m ∠ 1 + m ...
