Calculating Angles in Quadrilaterals WORKSHEET
Suitable for Grades: 7th Grade
CCSS: 7.G.B.5
CCSS Description: Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
Calculating Angles in Quadrilaterals WORKSHEET DESCRIPTION
Take a deep dive into angles in quadrilaterals with this worksheet.
In section A, students will find missing angles in trapezoids, parallelograms, and a kite before considering what they notice about these angles such as opposite angles being equal.
Section B is made up of three irregular quadrilaterals and learners will calculate one missing angle in each.
Next, in section C, students will combine other angle facts such as angles on a straight line and vertically opposite angles with what they know about angles in quadrilaterals to calculate missing angles in four multistep problems.
Lastly, students will show that a trapezoid is isosceles through a guided proof.
