Grade 4 Math · Lines, Angles and Symmetry
Build Grade 4 Math skills with five 10-question practice tests on lines, rays, line segments, angle types, parallel and perpendicular lines, and symmetry.
These Grade 4 Math practice tests help students identify lines, line segments, rays, angle types, and relationships between lines. Students also use lines of symmetry to describe matching halves of shapes.
A line extends forever in both directions, a ray has one endpoint, and a line segment has two endpoints. An acute angle is less than 90 degrees, a right angle is 90 degrees, an obtuse angle is between 90 and 180 degrees, and a straight angle is 180 degrees. A line of symmetry divides a shape into matching mirror halves.
