10/29 Lesson 3.2 2 1 What is the name of the angle pair, angles 1 and 2?
Watch it! Find mQRS.
Write it! Example 1) 4 3 m 8 1 7 2 n 5 6 If m<8 = 61˚, find the measures of all other numbered angles.
Write it! Example 2) 4 3 m 8 1 7 2 n 5 6 Alternate Interior angles are ____________. Alternate exterior angles are ____________. Same-side interior angles are ____________.
Watch it! Find each angle measure. A. mDCE B. mCBG
Work it! Example 3) Given m3 = 3x-1 and m5 = x+5. Find m1.
Work it! Example 4) Given m3 = 2(x-35) and m4 = x+15. Find m5.
Exit Slip! Let m1 = 120°, m2 = (60x)° . a. Give the name of the angle pair that describes <1 and <2. b. Write and solve an equation to find the measures of the angles. c. Name the theorem or postulate that justifies your solution. Find m3 and m5 if m3 = (45x + 30)° and m5 = (25x + 10)° .
