CCSS 7.G.2 Worksheets

CCSS 7.G.2 (Common Core, 7th Grade): "Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle." The worksheets below practice this standard. Each one is a free printable PDF with an answer key, comes in multiple versions, and can also be assigned digitally - no login or account needed.

Identifying Triangle Angles and Lengths

7g2

• Decide whether three given side lengths can actually make a triangle.
• Decide whether three given angle measures can form a triangle.
• Use the triangle inequality rule to compare side lengths and check if a triangle is possible.
• Use the fact that a triangle’s angles add up to 180° to check if a triangle is possible.
