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.
Congruent Angles have the same angle (in degrees or radians). That is all. ... the
same angle. Congruent - why such a funny word that basically means "equal"?
However, vertical angles always have a common vertex. Here, each pair of ...
Here, if we add in the angle measures, we'll see that vertical angles are
These names describe angles whether the lines involved are parallel or not
parallel. Remember that: ... If two parallel lines are cut by a transversal, the
alternate interior angles are congruent. ... Vertical angles are ALWAYS equal,
Proving that vertical angles are equal. ... Equation practice with vertical angles ·
Equation practice with vertical angles · Vertical angles are congruent proof.
When two lines intersect to make an X, angles on opposite sides of the X are
called vertical angles. These angles are equal, and here's the official theorem
Vertical angles are always congruent, which means that they are equal. Adjacent
angles are angles that come out of the same vertex. Adjacent angles share a ...
SOLUTION: 1. are supplementary angles adjacent. sometimes, always or never.
2. congruent angles are supplementary. sometimes, always, never.
Vertical Angles Theorem. Theorem: Vertical angles are always congruent. In the
figure, ∠ 1 ≅ ∠ 3 and ∠ 2 ≅ ∠ 4 . Proof: ∠ 1 and ∠ 2 form a linear pair, so by ...
