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.

Please select an answer first.
Correct answer: B
The correct answer is Perpendicular lines.
Lines that meet at 90 degrees are perpendicular.
Please select an answer first.
Correct answer: C
The correct answer is A line segment.
A path between two marked endpoints is modeled by a line segment.
Please select an answer first.
Correct answer: D
The correct answer is A ray.
A ray has one endpoint and continues forever in one direction.
Please select an answer first.
Correct answer: A
The correct answer is Line symmetry.
Matching halves across a fold show line symmetry.
Please select an answer first.
Correct answer: B
The correct answer is An acute angle.
60 degrees is less than , so the angle is acute.
A line extends forever in both directions, a ray has one endpoint and extends forever in one direction, and a line segment has two endpoints.
A line of symmetry divides a shape into two matching mirror halves when the shape is folded along that line.
