Your friend determines whether he can draw a triangle with angle measures of 50%, 60 and 70. 50 +60+70 = 180 Is your friend correct? Explain. Because the sum of the three angle measures is equal to 180, these angles will form a triangle. Draw a triangle with the given description. (6) two side lengths of 5 centimeters that meet at a 90 angle 7. side lengths of 3 inches and 4 inches that meet at a 1 10 angle Draw a triangle with the given side lengths, if possible. 8 3 in., 4 in., 5 in. 9. 12 cm, 12 cm, 15 cm 7 in., 10 in., 20 in. 11. 8 mm, 28 mm, 45 mm Draw a quadrilateral with the given angle measures, if possible. 12. 80%, 40, 80, 40 13. 909 904 909 90 - 14 150, 350, 1650, 1450 15. 30, 30, 150, 150 Construct a quadrilateral with the given description. 16. a square with side lengths of 3 inches 17 a parallelogram with side lengths of 6 centimeters and 10 centimeters 18. a trapezoid with base angles of 120 318 Big ideas Math: Modeling Real Life Grade 7 Copyright @ Big Ideas Learning, LLC Resources by Chapter All rights reserved.Name Chance B Date Lesson 9.5 Extra Practice Use the figure shown. Name a pair of adjacent angles. Name a pair of complementary angles. Name a pair of supplementary angles. Name a pair of vertical angles. Tell whether the angles are adjacent, vertical, or neither. Explain. 5. 95 Tell whether the angles are complementary, supplementary, or neither. Explain. 52" 65 11. Your friend names a pair of supplementary angles. Is your friend correct? Explain. LABC and ZEBD are D supplementary angles. Classify the pair of angles. Then find the value of x. 12 13 X / 32" 3x 2 x 1420 15 6 x ( x - 2) Complete each sentence with always, sometimes, or never. 16. If x and y are supplementary angles, then x is obtuse. 17 If x and y are right angles, then x and y are complementary. 18. If x and y are vertical angles, then y has the same measure as x. 9)If x and y are adjacent angles, then x and y are acute. 324 Big Ideas Math: Modeling Real Life Grade 7 Copyright @ Big Ideas Leaming, LLC Resources by Chapter All rights reserved.Date Name Lesson Extra Practice P + autside 9.3 2 Estimate the perimeter and the area of the shaded figure. 2.
