Finding the Sum of Interior Angles of Polygons

Grade 6 and grade 7 students plug in the number of sides in the formula (n-2) * 180° to find the sum of the interior angles of the polygons in these printables.

Partition each polygon into triangles and multiply the number of triangles by 180° to get the sum of interior angles. Frame the equation and find the value of x in these angles in polygons worksheets.

Unknown Angles in Quadrilaterals

Warm up to finding the measure of the unknown angle in a quadrilateral with these practice sheets! Set up the equation x + sum of the known angles = 360 degrees and accurately figure out the value of x.

Missing Angles in Parallelograms

Adjacent angles are supplementary, interior angles on the same side of a transversal sum up to 180°, and the sum of the interior angles is 360°. Use the facts to solve these angles in parallelogram worksheets.

Interior Angles of Regular Polygons

Compute the sum of the interior angles and divide by the number of sides to find the measure of each interior angle of regular polygons like pentagons, hexagons, and more.

Finding Missing Angles in Quadrilaterals | Algebraic Expressions

Prepare 7th grade and 8th grade children to work with algebraic expressions to find the value of x and then calculate all other angle measures in these angles in quadrilateral worksheets.

Finding Missing Angles in Polygons | Algebraic Expressions

Determine the sum of the interior angles of polygons using the formula, then add the interior angle measures and expressions given, and set up an equation to solve for x.
