Angle Review is a Grade 9–10 mathematics worksheet that strengthens students’ ability to identify and classify angle relationships. Across 10 questions, students distinguish adjacent, linear-pair, complementary, supplementary, and vertical angles; recognize specific angle pairs from labeled diagrams; identify a 90-degree angle; and select angles that are non-adjacent to a given angle. The mixed format includes six multiple-choice questions, two multiple-select questions, and two fill-in-the-blank items requiring students to recall that complementary angles total 90 and supplementary angles total 180. This free printable worksheet is useful for reviewing angle vocabulary, checking whether students can apply definitions to labeled angle figures, and identifying misconceptions before more advanced geometry work. It includes a complete answer key for efficient checking. Teachers can use it for independent practice, a short assessment, homework, or a guided review in which students explain why a selected pair is adjacent, vertical, complementary, supplementary, or a linear pair.

This worksheet practices identifying adjacent, linear-pair, complementary, supplementary, and vertical angles using labeled angle figures. Its 10 items combine multiple-choice, multiple-select, and fill-in-the-blank questions, including recalling that complementary angles total 90 and supplementary angles total 180. Students build skill by applying each relationship’s defining features to specific angle pairs rather than only memorizing vocabulary.
Introduce the five angle relationships with diagrams and have students state the defining evidence for each one: shared sides and a vertex for adjacent angles, a straight-angle total for a linear pair, opposite positioning for vertical angles, and 90- or 180-degree totals for complementary and supplementary angles. Then use the worksheet’s labeled-pair questions for guided practice, asking students to justify each choice before completing the multiple-select items independently. Finish with the two fill-in-the-blank questions as a quick check of the 90-degree and 180-degree totals.
Students may label any touching angles as a linear pair, even though the worksheet requires the specific linear-pair relationship, or confuse vertical angles with adjacent angles because they focus on the labels instead of the angles’ positions. In the multiple-select items, watch for students who choose too few or too many relationships or overlook the instruction to select all or three answers. They may also reverse the totals for complementary and supplementary angles, writing 180 instead of 90 or 90 instead of 180.
Angle Review is available as a printable PDF and as a digital quiz on Wayground, so you can assign the labeled-angle practice in the format that fits your lesson. It includes a complete answer key for the six multiple-choice, two multiple-select, and two fill-in-the-blank questions. Printable submissions can be graded by scanning student work with the Wayground for Teachers app.
In the worksheet’s Advanced Settings, adjust font spacing or font size to make the labeled angle questions easier to read, and enable a dyslexia-friendly font when helpful. You can also translate the worksheet into another language so students can interpret the relationship terms and directions more confidently while working through the multiple-choice, multiple-select, and fill-in-the-blank items.
