Definition and properties of vertical (or opposite) angles. ... Each opposite pair
are called vertical angles and are always congruent. The red ... Angle Types.
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 ...
The Congruent Angle Pairs. There are 3 types of angles that are congruent:
Alternate Interior, Alternate Exterior and Corresponding Angles. parallel line ...
Since the sum of the angles of a triangle is always 180 degrees. ... all the sides
are the same length (congruent) and all the angles are the same size (congruent)
Introduction: Some angles can be classified according to their positions or
measurements in relation to other angles. We examine three types:
Angles between two parallel lines that are cut by a third line. ... 3 angle 5 and
angle 8 angle 6 and angle 7. Recall that all pairs of vertical angles are congruent.
Certain types of angles, known as complementary, supplementary, and vertical,
... Vertical angles are opposite pairs of congruent (or equal) angles that are made
... That's because we know vertical angles (across from each other) always have
Vertical angles are pairs of angles formed by two intersecting lines. ... is just a
name given to a line that intersects two or more lines at different points. ... in four
corresponding pairs that have the same measure, so therefore are congruent.
