Free Printable Geometry Worksheets

Printable geometry worksheets covering angles, triangles, types of lines, and coordinate planes. Fresh randomized problems with answer keys. Grades 4–6.

About Our Geometry Worksheets

Geometry is introduced in 4th grade and builds steadily through middle school. Our geometry worksheets cover the four core visual skills: identifying angles (right, acute, obtuse, straight), classifying triangles by sides or angles, distinguishing types of lines (parallel, perpendicular, intersecting), and reading and plotting ordered pairs on a coordinate plane.

Each worksheet generates fresh problems on download — angles are randomized within each type, triangles and lines are shuffled so the order is never the same twice. Answer keys are included. These worksheets align with Common Core geometry standards for grades 4–6 (4.G, 5.G, 6.G).

Frequently Asked Questions

What grade level are these geometry worksheets?
These worksheets cover 4th through 6th grade geometry. Identifying angles and types of lines are 4th grade skills (4.G.1). Classifying triangles is covered in 4th and 5th grade. Coordinate plane work begins in 5th grade (5.G.1–2) and continues into 6th grade.
What is the difference between equilateral, isosceles, and scalene triangles?
Equilateral triangles have all three sides equal (and all angles equal at 60°). Isosceles triangles have exactly two sides equal. Scalene triangles have no sides equal — all three sides are different lengths. The tick marks on the sides show which sides are equal: one tick on each of two sides means those sides are equal (isosceles); one tick on all three sides means all are equal (equilateral); no marks means scalene.
How do I read an ordered pair on a coordinate plane?
An ordered pair is written (x, y). The first number (x) tells you how far to move right from the origin (0,0). The second number (y) tells you how far to move up. For example, the point (3, 5) is 3 units right and 5 units up. A helpful reminder: x comes before y just like x comes before y in the alphabet, and you always go across before you go up — like reading left to right.
