Finding Missing Angle Measurements
Transcript of Finding Missing Angle Measurements
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
x = 96 Quadrilaterals = 360! So... 70 + 70 + 110 + y = 360
140 + 110 + y = 360
250 + y = 360
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.
