Transversals
By: Morrigan Kenepaske
A transversal is…
A line that cuts through more than one line.
Parallel lines are…
Two or more line that never meet and stay
the exact distance apart.
Corresponding angles…
Are in the same position and they have the
same size – Angles 1 and 5, or 3 and 7
are corresponding angles.
Vertically Opposite Angles…
Have two lines that intersect to make four
angles, they are the same size, and are
opposite each other.
Alternate Interior & Exterior
Angles…
The interior angles is inside the parallel lines and
the exterior angles is outside of the parallel
lines. Alternate means on opposite sides of the
transversal.
Angle 3, & 6 are
alternate interior
angles.
Angle 1 & 8 are
alternate exterior
angles.
Complementary Angles
Two angles must add up to exactly 90°, and
they need to be connected by a ray.
27°+63°=90°
40°+50°=90°
Supplementary Angles…
Two angles in which the sum of them equals
180° .
