Transcript of Finding Missing Angle Measurements

Mini Quiz: Text About It! 0 + - = 9 8 7 1 2 3 4 5 6 c STOP!! Raise your hand and have a teacher come check your work so far. STOP!! Raise your hand and have a teacher come check your practice problems. Let's Review... Copy everything on this iPad. If you know the sum of the angles for a polygon, you can use an algebraic equation to find the missing angle. 1. Let's Practice... Follow the directions as you go through the presentation to fill out your worksheet. Finding Missing Angle Measurements Here are your practice problems: So let's look at a picture... In triangles, the sum of the angles equals 180
In quadrilaterals, the sum of the angles equals 360 Copy and label these pictures on your worksheet in Box A. a b c d e f n o p q r s t u a + b + c = 180 d + e + f = 180 n + o + p + q = 360 r + s + t + u = 360 Directions are always written in green, with the pin next to them (they look like this). Copy the following practice problems on your worksheet. Solve for the missing angle. Show your work. Check your answers. Good luck! x a z q w t 35 100 85 70 30 60 120 120 60 47 56 x 36 48 Triangles = 180! So... 48 + 36 + x = 180
84 + x = 180
(-84) -84
x = 96 Quadrilaterals = 360! So... 70 + 70 + 110 + y = 360
140 + 110 + y = 360
250 + y = 360
(-250) -250
y = 110 70 70 110 y Rewrite these facts is your own words on your worksheet. Bonus: And equilateral triangle has congruent sides and congruent angles. What is the measure of angle a? a 2. 3. Copy the problem and solve. b 105 95 79 63.2 33.4 r c 64 127 42 Answer this question on your worksheet. 1 2 3 4 5 6 7 8 a b c d e f a b c
