1 Unit 6 Trigonometry Right Triangles LG: I can use the Pythagorean theorem to solve for sides in right triangles

2 Right Triangle Terminology Legs Hypotenuse Angles of a triangle are labelled with a capital letter Sides of a triangle are labelled with a lower case letter (same letter as opposite angle) C AB b a c

3 Pythagorean Theorem “The square of the hypotenuse is equal to the sum of the square of the other two sides”

4 Practice Solve for the missing side x 6.0 m 9.2 m 27.6 cm 8.4 cm x

5 Skills Review: Unit Conversions! Metric Conversions Imperial Conversions 1 cm = 10 mm1 m = 100 cm1 km = 1000 m 1 m = 1000 mm1 km = 100 000 cm 1 foot = 12 inches1 yard = 3 feet1 mile = 1760 yards 1 yard = 36 inches1 mile = 5280 feet

6 Practice Make all units the same and then solve for the missing side 10.9 m 8100 mm x x 12 ft. 3 in. 5 yd. 1 ft

7 Homework Pg. 2 # 1-3 Pg. 3 # 1 - 3
