LINES AND
ANGLES
- Corresponding Angles
- Corresponding angles are the angles
on the same side of the transversal.
- Alternate Angles
- Alternate Interior Angles
- Angles opposite to each other in
the interior of the lines
- Alternate Exterior Angles
- Angles opposite
to each other on
exterior of the
lines.
- Co-Interior Angles
- Angles which lie between two
lines on the same side of the
transversal.
- Linear Pair
- Adjacent angles
which add up to 180°.
- Supplementary Angles
- A pair of angles
which add up to
180°. (They might
not be adjacent).
- Complementary Angles
- A pair of angles
which add up to
90°.(They might
not be adjacent).
- Transversal
- A line that intersects
two or more lines at
distinct points.
- Adjacent Angles
- A pair of angles
which have the
common vertex and
a common arm
- Vertically Opposite
Angles
- These angles are formed when two
lines intersect each other and form
4 angles. The angles opposite to
each other are vertically opposite
angles.
- Vertically opposite angles are always equal.
- An Angle is
formed when two
rays intersect
(meet) each other.
- Interior Angles
- Angles which lie inside
the two lines,
cut by the transversal.
- Exterior Angles
- Angles which lie outside the
two lines, cut by
the transversal.
- When two
PARALLEL lines
are cut by a
transversal many
properties come
in action.
- Each Pair of corresponding angles are equal.
- Each pair of alternate interior angles are equal.
- Each pair of alternate exterior angles are equal.
- Co-interior angles are supplementary.
- Parallel lines a lines
which never
intersect.
