February 9, 2010 Math 102 OBJECTIVE: Students will be able to find a missing angle when given angles of a quadrilateral AIM: How do we use subtraction to solve for the unknown angle of a quadrilateral? STANDARDS: 7.G.7 PRIOR KNOWLEDGE: Solve for n n + 65 + 110 + 75 = 360

The sum of the angles of any triangle is 1800 MINI LESSON: 1250 1100 750 A quadrilateral The sum of the angles of any triangle is 1800 The sum of the angles of any quadrilateral is 3600

To find the measure of angle A above: MINI LESSON: 1250 1100 750 A quadrilateral To find the measure of angle A above: Step 1 Add the three angle measures you know Step 2 Subtract the sum from 3600

T 95 60 80 What is the measure of angle T in the diagram above?

B 103 65 82 What is the measure of angle B in the diagram above?
