  1. Geometry Mini-Lesson A crystal rectangular prism measures 5 inches by 12 inches by 13 inches. The prism is divided into two congruent pieces by cutting from one edge to an opposite edge, as shown below.In square inches, what is the area of the new diagonal face formed by this cut? • 60 square inches • 65 square inches • 156 square inches • 169 square inches MA.912.G.5.4: Solve real-world problems involving right triangles.

  2. Geometry Mini-Lesson Line segment VL represents an airplane's velocity. The horizontal component, g, is called the ground speed, and the vertical component, r, is the rate of climb.An airplane takes off with a ground speed of 240 miles per hour and a rate of climb of 130 miles per hour. What is the velocity of the airplane, in miles per hour? C. 273 miles per hour D. 370 miles per hour • 110 miles per hour • 202 miles per hour MA.912.G.5.4: Solve real-world problems involving right triangles.

  3. Geometry Mini-Lesson Karen, who is 6.2 feet tall, casts a 7.0-foot shadow. She wants to determine the distance from the top of her head to the end of her shadow. How far is this distance? • 6.6 feet • 9.4 feet • 10.6 feet • 13.2 feet MA.912.G.5.4: Solve real-world problems involving right triangles.

  4. Geometry Mini-Lesson The sizes of computer monitors and television screens are found by measuring the length of the diagonal of the rectangular screen. The 15-inch rectangular laptop computer shown below has a height of 7 inches. What is the length of the screen? • 22.3 inches • 8 inches • 13.3 inches • 14.8 inches MA.912.G.5.4: Solve real-world problems involving right triangles.

  5. Geometry Mini-Lesson A farmer plans to fence in half of his rectangular field by running the fence diagonally across the field. How many feet of fence will it require to fence this entire region if his field is 280 feet by 165 feet?
