# [4.G.3-1.0] Lines of Symmetry - Common Core Standard

## By Freckle education

Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts.

# Identifying parallel and perpendicular lines | Geometry | Khan Academy

identify parallel and perpendicular lines

# Angles of Parallel Lines - Khan Academy

Angles of a transverse line when you intersect parallel lines are discussed in this video. Video discusses parallel lines and what a transverse line is. Video then goes into labeling the angles, such as corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The video shows how to find the measurement of each of the angles using what you know about angles and lines. Good review for concepts of angles and vocabulary associated with angles. Good quality video. Good for middle elementary and middle school students.
